It is very nice book all the fundamentals are given properly example are set, concepts are written very well and the language is very supportive the book is a one kind of antibiotic medicine which helpful for multiple aspects of Physics learning. May this book become the best seller!
You will not find better books in physics than by Profs.S P Neelam and Shriram Hegde where fundamentals are beautifully explained with quantitative and qualitative analysis taking care of physical elaborations and mathematical extensions !!
It is a very well written book with a good choice of illustrative problems that will clear the concepts and build the problem solving ability as required at JEE Advanced level. The students may either use them for self study or an additional to their coaching material.
The best book beyond trace if doubt. Just read it, you are bound to learn. Concepts get imprinted in mind. You will flow with the concepts. Written in creative manner. Examples are chosen cleverly and intelligently. Very good solved examples. Very good exercise. They cover all concepts and sufficient. Better than other available books.
The best book I have come across in my 22 years teaching career for IITJEE. Development of concepts is unique, solved examples are well graded from the easiest to the toughest, required for school exams, IITJEE and Olympiads.
Here is my assessment of the books students mostly use:
1. NCERT Textbook 4/10
2. University physics by Sears & Zemansky 5/10
( Heat and Thermodynamics, and Optics lessons are better, almost 7/10)
3.Physics by Resnick @ Halliday 7/10
4. Textbook of Physics by Neelam &Hegde 9/10
This is certainly the most useful book for school syllabus, IITJEE, NEET and various Olympiads. Definitions & concepts, selection of illustrative problems and problems for practice in exercises, all features of this book are distinctly better than other books.
Contents of Newton’s laws, Dynamics of Circular Motion,Centre of Mass,Rotational Dynamics, Gravitation, Fluid Statistics and Surface Tension are matchless and not found in other sources. As a physics teacher for IITJEE and NEET I can say that this is best book of its genre.
Five features of this book are outstanding.
(1) The book addresses the key question – how to learn physics. It makes a student learn physics in best possible way.
(2) It keeps the student always motivated and confident, student never experiences any frustration.(3) Underlying principles and strategies for simple and complex problems are explained using the same basic approach.
(4) It focuses on typical student misconceptions and problem areas.
(5) Skills and techniques covered in previous chapters are intelligently related to the understanding and knowledge of the current chapter. Multiple concepts and mathematical steps are explicitly explained.
Distinctly better book. Must read.
A unique book of its kind. One strength of this book is that is that definitions of basic concepts like displacement, velocity, force, centre of mass, torque etc are dealt with crystal clarity and rigour. As a result, solving problems becomes really easy as you see that it is just a matter of applying laws involving these concepts systematically. There is no scope of confusion. The authors also give a nice background before introducing the technical definitions. This gives a good intuition about the concepts and a better understanding of scientific method. I have not seen other books doing such a good job teaching the subject. A must read.
In my view the quality of book of this category depends on the contents of two topics – Dynamics of Circular Motion and. Rotational Dynamics. On this count this book is extraordinary, a perfect 10.
After so many days a book in physics which is really meant to learn physics rather cramming. Neelam sir is a god gifted professor who has the ability to formulate tedious questions into a very easy to grasp solution.
Authors are very clear in their head.They know very well needs of different students. They have included plenty of NCERT level problems, IITJEE type problems and some Olympiad level problems in increasing difficulty order. Authors have solved even NCERT level problems in a very elegant and informative way. Best book for understanding physics and clearing all concepts.
The book mechanics volume 1 written by sp neelam sir is outstanding book. Before this book i had many books and had a great experience throughout.
After this book i can say easily that if u hate physics or dont have intrest go for this book right now. The book form is so well managed that it can create intrest for physics in students as well as for teachers. I own solved many questions from this book and i am surprised that book covered every single concept of jee or neet.
In last, finally a book that has a good number of numericals,theory and concepts.

I recently went through Volume 1 of the book “Textbook of Physics” by SP Neelam and Shriram Hegde sir.
I have been teaching for IIT JEE for the last 14 years and i have rarely seen a book written in such a beautiful way, explaining the minutes details in such a lucid manner.
Solved examples have been very carefully chosen and the way these are used to explain different nuggets in a chapter makes it stand apart.
Solution of these examples feels like a teacher is explaining things sitting besides you.
Even if you have studied a chapter, i am quite confident that this book will make you richer in new concepts and you will get different ideas to ace a problem.
Moreover, collection of unsolved problems at the end of the chapter are amazing. If you are looking for good level problems in a chapter which cover all the aspects, you must give it a try.
At last, i highly recommend this book for all the serious aspirants of IIT JEE and physics Enthusiasts.

Book Preface
This book is intended for those school students at senior secondary level who want to pursue a career in science and engineering. It is for those students who prepare for IIT-JEE (Main and Advanced), Olympiads and other exams, and who find physics interesting but hard to follow.
Problem solving, I believe, is an art not very hard to master if you are exposed to all kinds of problems right in the beginning. This book is there to expose you to the a range of problems. Unique and genuine problems need ingenious solution techniques. A problem approached with the right strategy can save both time and effort.
In this book, multiple solutions to the same problem have been explored by applying different concepts in physics. This not only broadens the imagination and understanding of students but also develops an intuition to figure out the best approach.
Simple mathematical manipulations, solving for unknowns from simultaneous equations and basic differentiation and integration have largely been left for the students. Mathematical simplification steps are given in detail only in specific cases where special techniques or non-standard methods or smart shortcuts or intelligent guess-work can reduce the solution to a few basic steps.
Though I have tried my level best to edit and eliminate all types of errors, a book of this nature cannot claim to be without errors. I would be glad to receive your comments in order to make the necessary changes in later editions.
I am grateful to Prof Sriram Hegde, IIT Delhi, for many prolonged discussion sessions I had with him, for his valuable suggestions and guidance and also for his constant motivation. I will be failing in my duty if I do not acknowledge the efforts of Srija Anand and Rishabh Singh for painstakingly going through the draft, suggesting corrections and modifications. I owe my sincere thanks to Dipesh Kumar Aarya for beautifully typesetting the book. Last but not the least, I wish to express my sincere thanks to those who contributed directly or indirectly in making this book a reality.
