Textbook evaluation of "An Introduction to Physics" (Glover & Sugon, 2017) by Davao STEM teachers

Fr. Franciso Glover, SJ together with the STEM teachers during the Ateneo de Davao STEM Physics 5-week workshop last April 14 to May 26, 2017. The photo was taken by Dr. Quirino Sugon Jr when he gave a short talk on physics to the teachers last 12 May 2017. Textbook signing by Fr. Glover and Dr. Sugon followed after the talk.

: C & E has provided you with the free copy of our textbook An Introduction to Physics as well as morning and afternoon merienda. If you feel grateful to C&E, can you express that gratitude in a specific and unique manner: help them improve future editions by sharing your honest evaluation of every aspect of the textbook, e.g. clarity of explanation, student-appeal, what sections you find particularly difficult, most attractive, topics you feel should have been included or omitted, etc. Please don't just say "Okay, lang," for this won't really help them sell more books in the future and make gobs and gobs of money. ☺--Fr. Francisco Glover, SJ
Note: the following evaluations were copied verbatim with only slight editing. The names identifying the authors of the comments were removed.

"An Introduction to Physics" by Fr. Franscisco Glover, SJ and  Quirino Sugon Jr. (C & E Publishing, 2017, 575 pp).

1. Different from the book I bought

For the book I find it different from the book I bought in other store maybe because of the integration of calculus.

The book open my mind on the reality of physics world and how to become a competent and a better teacher to my students. Father Glover is really an inspiration for all of us. Once again the book is different because of only one person: it's the book of Father Glover. Having acquaintance with the author and a lecturer is really a memory that cannot be forgotten and I will share this memory with my students.

Over all the book is a book of memory and love. About the content I will not going to say anything but I will use it for the future / rather for the opening of the school year.

Thank you!!

2. Concepts and definitions should be in bold

I would like to thank C & E Bookshop for giving a copy of the book. The following could be improved:
  • Concepts and definitions should be in bold or italized so it can easily be seen when scanning the book.
  • Explanation of the cover page should be added at the back cover
  • Primary equations should be in a box with labels
  • Please add table of formulas and constants at the end of the book
3. Really informative and substantive

My warmest gratitude and appreciation towards C & E Bookshop in partnership with ADDU for giving us a free copy of the book and for sponsoring our morning and afternoon merienda.

Personally, I find the book really informative and substantive when it comes to the content explanation. The book seems to have lengthy text and for students who are not into reading long text, they may find it unattractive but actually the long sentences are fun to read because the authors are like story-telling. They explained the topics thoroughly as if they are talking to the readers. It's excellent to note that the book is in compliance to the DepEd Curriculum Guide so there's no question when it comes to the presentation of included topics. 

Honestly, Physics really is difficult subject and as a teacher, it is my responsibility to learn and love the subject so that I can give my students an effective and interactive learning experience in taking the Physics subject. The cartoons and illustrations are good diversion of attention for students to look into because aside from the humor that it shows, it appeals to the learners the important concept behind the silly drawings. The poetic introduction that comes before every unit of the lesson is also commendable because it helps students appreciate the art in Physics. That way, students can realize that learning Physics is not a misery but a mystery of the world we're living in that is being revealed.

Lastly, I just want to acknowledge Father Francisco Glover and Dr. Quirino Sugon for writing this book that is meant to be taught to the Filipino Senior High School students. I just hope that C & E Bookshop will be able to produce this book at a low cost so that more schools especially the Public school students can afford to buy this book as a reference.

Thank you very much!

God bless you!

4. Helpful to all STEM students

The book is very helpful to all STEM students because it covers all the topics in physics and it is presented in a friendly way in which the students can understand it easily. What I like most is the part where there are supplementary lessons or enrichment part of the books which helps students to understand the topic well.

I suggest that there must be a part in each chapter a "key terms" section pointing out important words or terms in each topic to help the student understand and appreciate the lesson.

5. Clarity of explanation

I am thankful that I belong to this five-week workshop on STEM Physics. I have learned a lot on this workshop. Thank you for supporting this training for giving unlimited snacks and of giving of the free copy of the book.

In terms of clarity of explanation, it was well done, some topics were highlighted to give emphasis of the topics being discussed.

Student-appeal. My first impression of the book, it looks it was verbose but if you read it already you can easily understand. May I suggest that cartoons given will be colored one, to be more effective to students.

For me the difficult part in the book is that there we're no given example problems in each topic, for the student to be given in solving the problems.

Most attractive--cartoon character presentation.

Thank You Very Much and God Bless Us Always.

6. Suited to Senior High School STEM learners

The topics presented in the book and manner on how it is being presented is suited to the Senior High School STEM learners.

I observed that approach of the book is conversational and that made me enjoyed reading.

The items after each chapters such as the Test Yourself, Discussion and Exercises helps the learner of the the book evaluate himself. Another unique section that the book has is the "If You're Interested" section which allows the learners to explore more on the topics.

Personally, the book is something I am I have now, most especially having it for free. The section "A Bit of Calculus" was impressive because it is very helpful to aid our weakness.

I strongly recommend the book to be used by all public and private Senior High School offering STEM around the Philippines.

7. Very student-friendly illustrations

Thank you C & E Bookshop for the copy of the book and the merienda. Thank you for believing in Fr. Glover and supporting him in his legacy. Please do help too in improving the book for future generations. The drawing illustrations are very student-friendly, its good I might not know everything in the book, if its too difficult or easy, but I believe if students do have the foundation at good physics since junior years, the content of the book will always be helpful too. I will try my best too to deliver and transfer learning to students so at least they will love physics and education.

I believe you have witnessed Fr. Glover's love for teaching and again thank you for granting his might last will. Father God bless is always.

8. Conversational presentation

The textbook is very commendable because the manner of presenting ideas/clarifying concepts are conversational as if the author communicates you by the heart. I how the author attacked concepts in such a way that he is just beside me telling.

The illustration of concepts are good because you will be able to understand well the concepts. The ideas/topics are properly sequenced following the standards and competencies set by the Department.

The Test Yourself and Drills are thought provoking in such a way it sorts all your imaginations to think and motivate you to solved the problems given.

I capulises[?] the entire competencies to be covered by students enrolled in the STEM Physics.

Congratulations Fr. Glover for such comprehensive concepts deliberately presented in such a way that students will learn in accordance to their own intellect and for living such remarkable and commendable project.

9. Many will purchase this textbook

C and E Bookshop. Thank you for your TRUST to Father Glover (and to his Physics textbook). I am sure that a lot of Ateneans and non-Ateneans will utilize, THUS, PURCHASE this textbook.

Thank you so MUCH too for the MERIENDA that you shared to us--really brought our morning and afternoon delightful treats that energized us in a BIG WAY!

For the Textbook. Brilliant contents, felt the "compliant following" on the competencies, suggested by the DepEd Office.

  • Make the "character size" larger
  • Maintain the provision of the space for the student's NOTE-taking
  • MORE MORE CARTOONS, making it more fun
3D Drawing. Colored (for the next edition).

The fraction statement. Please don't do something like this:
1/2mv^2 + 1/2mv^2 = 1/2 mv^2 + 1/2 mv^2
but the UPRIGHT style one like: $\frac{1}{2}mv^2\ldots$ or
\text{Energy Density} = \frac{1}{2}\frac{1}{\mu_0}B^2
Not like this
\text{Energy Density} = (1/2)(1/\mu_0)B^2.

But, for anything else, Father Glover inculcated love and passion to us. Thus, WE WILL JUST RETURN the favor.

Thanks C & E.

Thanks Father Glover.

Thanks Physics Department.

Davao STEM Physics teachers at Ateneo de Davao University last 12 May 2017. They were the evaluators of the textbook An Introduction to Physics (Glover & Sugon, 2017).

10. Explained the physics topics well

First of all, providing us a free copy of the said Physics textbook is highly appreciated and me, myself is very grateful because I am one of the lucky ones who received the very first edition of that said Physics textbook authored by Father Glover and Dr. Sugon.

In terms of the "clarity of explanation," even though there are some corrections, the book explained the physics topics very well, however, there are some inconsistency of the physical quantity/notation wherein the students might somehow confused about it. But nevertheless, it is very good.

I guess students will like it because everything is in there. It follows or aligned with the said competencies imposed by the DepEd. Compare to the other books, this one has a few pages but the content needed to be learned by the students are all there.

11. Not the kind of physics I learned in the past

Looking at the book, I ask myself can I teach physics. It is not the kind of physics that I learned in the past. Before it was simple. But now Calculus based. But during the duration, I was able to get information and learn to love Calculus. That is why I told myself again. I can teach not only Physics but also Calculus.

The most difficult sections to me are the sections related to Optics particularly ray diagramming. Very attractive to me is Electricity and Mechanics.

I would like to suggest to include topics on Nuclear Physics and Quantum Mechanics.

Thank you for the book.

12. Poses a challenge to its readers

The book poses challenge to its readers though we know that Physics in itself is a challenge. The reader in this case is advised to have already grasped essential foundation of the subject. I actually appreciate the book gives a comprehensive explanation (at least descriptively) of the topics, but when the topics seem to be too technical, the reader I think may get lost in the process. Another, the book's contents are already aligned with DepEd's learning competencies, but if the reader (i.e. students) have not been familiar with the terms or their math is not strong, a problem may exist.

I believe that this book is a rich source of information, and I believe the reader will entirely be supplemental in understanding, solving problems and appreciate things related to Physics. I hope that this book will have its second edition.

13. Significantly complex explanations

  • The explanations presented in the book was significantly complex compared to the high school physics books but manage to bridge the gap left by this SHS STEM curriculum.
  • It might not be overly appealing to students especially those who have weak foundations in Math and in JHS Physics. But the explanations and ``silly'' little cartoons help ease out the learning curve.
  • I find the topics on optics and electromagnetism most attractive, and the extended explanations about the derivation of formulas will be very needed later. I would have to brush-up on my mathematics.

14. Arrangement of topics has continuity

I would to say thank you C & E Bookstore for giving us the copy of the book and the merienda.

The topics were arrange in such a way that the students apply the previous topics to another, it has the continuity and well arrange. I like the exercises because the students can always check answers themselves. Some of the questions has the specific clue or hint for what section of the book they are using and so that they could have an idea on what formulas to use and in this way the knowledge can be reinforce given they are studying at home.

Hopefully, they can release a manual of experiments that can be useful in public schools or they could include some drills and experiments in the back.

15. Very conversational

As I've noticed the textbook is very conversational that the students will love to open and read it. The exercises are very challenging.

Reflection and refraction topics are very interesting. And also the ELECTROMAGNETISM.

I recommend the book to be used in both private and public school.

Energy in small packages: an introduction to quantum theory. This is the upper half of p. 269 of "An Introduction to Physics" by Fr. Francisco Glover, SJ and Dr. Quirino Sugon Jr. (C & E Publishing, 2017).

16. Appealing illustrations

Areas to celebrate:
  • Appealing illustrations at the side
  • Easy to understand and simplified explanations
  • Very readable font and sizes
Areas to improve:

  • Nice to have an appendix or table that summarizes key formulas, constants, units, and conversions, etc. for the entire textbook
  • Some sections are too short and may not be enough to fully explain interesting points
  • Some errors are expected in the 1st edition print

17. Should undergo proofreading

Thank you C & E for providing us a copy of the book. Well I guess the book is really suited for senior high students. What I want to suggest are the following:

  • The book should undergo proofreading to find any possible errors which are not found yet so that the next printed copies of the book will be free from any type of error
  • I think these is a need to review (the i') some of the items in the Exercises because I found some items difficult to answer because (JUST FOR ME) there is a little ambiguity on what the item really wants to draw as answer.

Thank you Father Glover, Ma'm Carnicer, Sir Eldon and Sir Philip for this opportunity.

18. First time I owned a Physics book

Thank you very much! That is the first words that I want to say. This is my first time I owned a book in Physics, so thank you very much.

As for the contents of the books, I can say that these would really help me in my teaching of physics because the contents are aligned with the competencies and content standards we have in our  CG of Physics I and II. In addition, I like the exercises being presented which has also it answer key. It will help me and other teachers validate the equations/formulas we are using as we give these to our students. The provision of related lessons like if we want to dig in deeper is also commendable.

The only thing that needs to be improve in this book for me is, that the contents specially the key concepts can still be summarized as to get the idea and concepts easily. Also more illustration can also be presented for the students to understand much better.

Thank you!

19. Make the font bigger

The Book:

  • Font size. Can the font size be made a little bigger?
  • Equations. Can the mathematical equations be placed always in the center separately and the steps be written vertically?
  • Content. Though I did not compare yet the content of the book from that of the Dep Ed Curriculum, but I suggest that this should be met so that the book can be used as textbook nationwide. Can the definitions be labeled? i.e. Defn 1.1 Maes$\ldots$
  • Teacher Edition. I suggest that there are printed teacher edition books to be given complete with test banks and answer sheet. 

The Foods:

  • The foods are nutritious and balance. I suggest that the drinks, as well, are nutritious. Bottled water will suffice.

20. Unlocks difficult concepts

I am so blessed to avail the opportunity of attending the five-week seminar with free snacks, lunch and most of all the different instructional materials especially the Physics book. I would like to write some good points and ``something'' that needs to be improved (if there are) about the book.

Good points:

  • It unlocks difficulty of understanding concepts (imaginary).
  • The illustrations help a lot in drawing ideas.
  • The connectivity of the equations and formula/s help make the concepts understandable.
  • The self-test with answer help me (new to this field) do the operational way of solving the problem more easy.
  • The part of the book (If You're Interested) make the book unique in itself and very helpful to the teacher. It provides additional knowledge/information that can be used in presenting the concepts to the students.

``Something'' that needs to be clarified (sorry if I am wrong):

  • The use of the letter representation. Like for example $s$ and $v$ for speed; $s$ and $d$ for distance; $w$ for weight or omega.
  • I dont think that all of what is in the book can be given to the students knowing that there are many competencies to be accomplished for a given alloted time.

21. Understand Physics more

To the C & E Bookshop, I would like to say thank you for the opportunity to be one of the trainees in STEM-Physics Workshop. This is a good avenue for me to understand Physics more than I do, for giving us books (references) and other lab materials which can be of help to us teachers particularly those in public schools. The training for which you have sponsored/provided broaden my knowledge, understand those least understood lessons at the same time allowing me to meet new friends which can be help me whenever I need them (they are just a text away!).

Throughout the course I gain weight (5 kg) which is a sign that we are fed well. Thank you so much and more power. Hoping for another training such as this in the future.

22. Worth our take!

The textbook is worth our take! The author, Fr. Glover, we had a personal interaction with him, and that makes it so rare and opportunity as physics teachers. Like the placebo effect, the contents will have or will eventually become systematized or absorbed because the author is just right here with us who is so accessible and accommodating. Just like any Physics book, the concepts are presented with attempts of simplifying them with equations and cartoons. The unique thing there is we were able to come in contact with the author. Well, along the way, when we will have a thorough entanglement with each page, each line of the line we may encounter some setbacks and according to Fr. Glover, it will just mere e-mail away with him. That's how and when he can extract the possibilities of better understanding the ideas presented in the book. It's a higher dimension in Physics though. However, there are things that can be supported by Ask To top it all, the book becomes a cherished possession, as this will also help us in our journey to helping others become physics enthusiasts all the better, all the more. It will serve us an inspiration as we can all exclaim that hey! The author was our professor--great, has the mark of a scientist, a blue-blooded physicist.

23. Difficult in mathematical aspect

I am so proud to be a participant of this training, and being an evaluator of this book. Even though this is not my field of teaching but then eager to learn about physics. Regard this physics book I find it very difficult in mathematical aspect but the context is very plausible. Maybe it could be better if there is a detailed elaboration on the solutions of the problems given in each Chapter.

24. Understandable by STEM students

What I like:

  • The book presented the topic/concept in such a way that it will be easily understood by the students (STEM students)
  • The cartoons in the textbook gives an impression that Physics is not really a hard or serious subject. Physics is fun.
  • The right-hand rule which is clearly presented in the book is a big help for Physics teachers and STEM students to easily understand the topic/concept.

Things to improve:

  • The kind of paper used in the textbook if possible is a glossy one.
  • If possible it is hard-bound so that it will last longer.

25. Explanations sometimes too hard for students

Book was very helpful in learning and understanding the lessons

  • The book sometimes explains concepts in a way that would be too hard for students to understand
  • I find the section on electricity a little difficult. I hope there was a little more illustrations and sample problems on the book.
  • The topic on motion was the most attractive. It had examples on different problems.
  • I believe the content of the book is already enough since it tackles all things related to physics.
  • Continue on putting activities and exercises since it will help both the student and teacher in grasping concepts. It is also a way of knowing which concepts in the lesson was hard for the students

Thank you.

26. Language is a bit scholarly

It is indeed a privilege to have an opportunity such as this. My kudos to the C & E team for catering us in this 1 month journey. But just like any other kind of endeavors, there are some minor improvements to make.


  • The language used is quite a bit scholarly which is from a PHYSICS TEXTBOOK. This could be improved if the teacher will add further illustrations, gimmicks, etc.
  • It would be better to include a lot if not several chapters on MODERN PHYSICS. (This would greatly help students$\ldots$)
  • Links to websites could also be added to deepen the understanding of each topic.
  • Several or chapter by chapter experiments or Do-It-$\dots$ Activities could be provided for full appreciation of $\ldots$
  • Derivation of several formulae could be included as its accompanying figures and diagrams
  • $\ldots$ the prescribed curriculum guide (CG) of DEPED. This could really help teachers in the process.
  • Students could also appreciate the book better if there will be more comic illustrations which correlate to the competencies of DepEd.


27. Somewhat unique presentation

The textbook for me is somewhat unique in the way it presents its idea. The topics are finely knitted to produce a smooth transition between the topics. The printing was also good.

To shorten my evaluation, these are the + and - comments about the book:

(+) comments

  • It’s free!!!
  • The manner in which the ideas are presented is brilliant.
  • The cartoons are eye-catching.
  • It really does follow the curriculum guide that the Deped uses.
  • The diagrams.

(-) comments

  • The errors

28. Main formulas should be highlighted

Thank you C & E for the AM and PM snacks as well as the bottomless coffee, milk and choco drinks :)

For future editions of the textbook, I suggest that the main keyboard and formulas will be highlighted or even in BOLD format. The index page is also needed. Thank you for publishing very detailed and explained concepts in STEM Physics.

29. Hard to understand

I am very lucky that I received copy of your book. I am also thankful for the morning and afternoon’s meriendas. As I browse each pages of the book, I found it hard to understand, but it is understandable because I have little background in Physics. The graphics are good but the font size is small. The cartoons are very helpful in understanding the topic. As we navigate the book, we found corrections and I hope it was already addressed. All the topics are important for the learners.

30. Very much helpful

The textbook given to us is very much helpful to us especially in the school wherein the Deped doesn’t provide us the textbook for our senior high school. With regards to the content it does provide the context that is aligned to the curriculum guide of the subject itself. Since physics is a very difficult subject to encounter, I would suggest that there should be more problem solving after the content of each topic with the process on how the equations was derived and why does it happens so. I appreciate most the book because it’s making it’s way on how to understand physics in easy way. Thank you Ateneo for giving/providing this book for us! Mabuhay! More power!

Davao STEM teachers during the 5-week STEM Physics training at Ateneo de Davao University. The picture was taken last 12 May 2017.

31. Presented in Philippine context

I like the way the cartoons were presented in the book. Even the pictures because it is very realistic and presented in localized manner (Philippines context) unlike other textbooks which are usually westernized.

I also like the given problems in the exercises because the given values are small (mostly 1 or divided by 1). This will not discourage students w/ no calculators (like one for the duration of the training) because I think the most important part in doing exercises is to check the correct concepts of physics rather than mere calculations. As a physics major, I find this book very refreshing and I hope I can apply to my school this year, because it is seldom that I see textbooks that explains and put more emphasis on the concept rather than the skill in doing mathematical calculations.

I would like the book to place some trivias or facts about the story of each discovery or how the scientists discover certain constants or concepts (i.e. how Maxwell arrived at the speed of light or why Max Planck was sad as indicated in the book). This way the students can not only view the scientists as some abstracts individuals but as human beings. This will help them reflect on scientific attitudes.

32. Very few examples or sample problems

Points for Improvement:

  • There are very few example or sample problems in each textbook.
  • There are lacking equations which are needed in order to solve the exercises.

Points worth emulating:

  • The integration of other topics in a particular section is good. The students will be able to see the applications.
  • The topics are properly explained.
  • The cartoons help a lot. :)

33. Good explanations for beginning teachers

The quality of explanation of the textbook is quite good for me as a beginner to teach PHYSICS in STEM SHS.

I found it interesting at first and I am eager to study for the next chapter if you have time to read  the textbook, a very nice one source of learning.

There are sections in the textbook that I found it difficult to understand especially in the background of calculus but I actually found it interesting.

34. Unreadable light blue text

The textbook has light blue color of words in each page, for me I couldn’t read it for a long period of time is it okay if its color black.

I’m not a good critic, but is it really the authors’ own words and description of terms? Or just refer to other author? I mean no bibliography? Perhaps I don’t know the source?

At the back please write the answer for discussions and exercises please.

The book is a complete package based on the curriculum guide (DepEd). All the contents are there and our teacher is the author.

The Ateneo way…

35. For highly intellectual students

Give more examples/solved problems.

The book is highly recommended for highly intellectual students.
Every lesson should have an example from simple, average, and difficult examples.

36. Drawings caught my attention

Thanks for the copy of the book and merienda. I really like the drawings in the book. It caught my attention and I think maybe the student might appreciate it and continue reading the book. About the content, well it is non-traditional compared to the other book in the market (in terms of delivery). I find it nice that a new approach was taken.

37. Well-explained

I. Clarity of Expression

  • well-explained

II. Student Appeal

  • I love the cartoons and images in the book plus the verses/poems on the beginning of the chapter. For me, it can draw a student’s interest

III. Sections I found difficult

  • Electromag. maybe because, I didn’t like the topics well (not due to the book).

IV. Most attractive part

  • The beginning. The chapter where space, time, etc. are given light.

38. Teacher-student friendly


  • I really like the book, it’s teacher-student friendly.
  • Examples are given with answers. There are lots of exercises.
  • Overall, its (the book) worth recommended! :)


  • More examples with answers for teacher’s use :)
  • More activities not just purely problem solving.
  • More color/picture for situational examples to make it more attractive for students.

39. Organized content flow


  • The outline and the flow of the content/topic in the book is organized.
  • I like the caricature/illustrations.

Things to Improve:

  • Provide more word problems.
  • Some topics are very wordy.

40. Simple yet elegant cover design

First, I like the color and the design cover of the book, simple yet elegant. The book is obviously detailed (though it is already a summary). The space also beside the text is very helpful for note-taking. The page quality is also good. I believe clerical errors can still be improved. For improvement only is the format of the equation please use the new one . Simplify the text with many illustrations. I guess it will be student friendly. Add more sample problems with illustrations.

41. Some formulas not explained well

For the textbook, some parts are easy to understand but some formulas stated are not explained well (for a first-timer in physics like me). I hope that when the equations/formula is presented, the representation of variables are also shown. :)

42. Sufficient knowledge of every physics discipline

The book provides sufficient knowledge for every discipline in physics. It was totally great.

43. Total learning package

The book as a whole is a total package of a learning tool. But I would like to see the book in the future to have more examples with solutions so that the students can understand the topic more even without the explanation of the teacher. And for the Filipino learners, it is a great privilege to have this book because much will be learned from this.

44. Simple and attractive cover

I am so grateful to have a copy of the book and it’s my honor to be a part of this evaluation. The totality of the book cover was simple and yet attractive. The presentation of the pages were visible to the eyes. The arrangement of grammar is easy to understand, the additional graphics or animated help the book to be more attractive to look and read. I like also the additional information about the life of some scientists that contributed a lot in the field of physics. For me all the topics were important and should be included in lesson guide. The book is presentable and friendly to the eyes of the student.

However, there were some sections that typographical errors, some of the words were lengthy and long. If possible, make it simple and direct to the point. There were also numbers or constant value that were confusing because it was not constant to all the pages. And last thing there were some answer keys that provided at the end of the exercises is not correct.

To summarize everything the book help a lot the students to be more interested in the topic physics. The appendices help them to locate what are the constant values that can be apply to a certain equation. Motivates that student to familiarize and develop critical thinking and logical reasoning.

May God bless your company and God Speed.

45. Explains major concepts clearly

So far when I was using the book throughout the workshop, I find it very very useful and it was able to clearly explain major concepts in introductory physics. The book started with the concept of space and time where these two entities were not scientifically explained and introduced by other books.

For student appeal, I see it very engaging since the cartoons are right for every topic discussed however it may be good also to add colors to the cartoons, drawings, graphs, tables, and equations to emphasize certain points. Each page will also look attractive for students to read.

It would be better also that a quick review of algebra, geometry, trigonometry, graph analysis, and basic calculus be placed before starting with chapter I so that students are thoroughly prepared and oriented about the essential mathematics to be used throughout the entire book or course so that it would not be difficult for them as they progress with every chapter in the book.

Every topic is very interesting and I don’t think we need to omit some topics but giving suggestive readings on a certain topic is another way of helping students expand their learning and become more interested with physics.

46. Helpful for public school teachers

The textbook is really helpful especially to us from public school since we don’t have references or modules in physics up to this time. We highly appreciate the efforts of the authors, Dr. Sugon and Fr. Glover, who unselfishly shared their expertise in the subject. Thank you so much for all of your kindness and generosity. The book shed us light in understanding physics concepts the easier way.

Much as we like the book, it could have been better if there’s an inclusion of laboratory activities within the book or published on a separate manual so that application of concepts will be further appreciated by the user/learner.

47. Intertwined but seamlessly weaved topics

This is the first time that I encountered a physics book with topics intertwined with other main topics but seamlessly weaved together. This is the book that I cannot find a separate section of energy, work, projectile and others but does not mean these are not found in the book but instead embedded in a particular chapter they are appropriately linked together.

However, the details on how the major formulas are being derived are missing. For the future editions of this book, hopefully it will be given emphasis considering that the readers/users are still in their senior high and they are coming from different schools and backgrounds.

The last page and cartoon of the main text of "An Introduction to Physics" by Fr. Francisco Glover, SJ and Dr. Quirino Sugon Jr. (C & E Publishing, 2017, p. 556). "We have seen only an introduction to the wonderful adventure that is physics. The quest continues. Physicists are still turning outward into space, and inward toward the nucleus, the heart of the atom, still seeking to know more and more of the world about us, ever striving to come to a deeper understanding and appreciation of the wonderful works of God."
