Physics | Resnick Halliday & Walker | IIT Books

Hi everyone In tis Post I am Sharing a extraordinary book for JEE Aspirants .
It is a book of Physics named - Resnick Halliday & Walker.

WHY THIS BOOK IS SO SPECIAL AND POPULAR AMONG JEE ASPIRANTS?
To answer this, I would like to share my personal experience with this book. I am that kind of person who didn't believe in the theory and text written until I see any photo proof related to it. In this book, in every theory part and topic, you will see a wide variety of photos related to that particular topic and the speciality is that most of the photos are Coloured.
Yes, you read it right, the photos mostly are in colour. And the language in the content text is so easy, as i have seen most students say that the foreign author's book is tough to understand. But this book is totally written is such way that we can read it easily and its coloured pictures develops interest in studying that topic.
That's why it is so popular among students.
But you have devoted a lot of time in studying it's theory although it is easy but still it is explain in a little bit deeply so more the time you study it, more your topics will become strong and you will have a better grip on the chapters. Also, a lot of solved and unsolved examples and questions are given which are very good and sufficient to practice. This book has covered all the topics of 11th, 12th classes as well as more information is also given in this book. This book is all-rounder if you study it properly. That's the reason this is one of my favourite book.

Now, What Is Physics?

According to this book, Science and engineering are based on measurements and comparisons. Thus, we
need rules about how things are measured and compared, and we need experiments to establish the units for those measurements and comparisons. One purpose of physics (and engineering) is to design and conduct those experiments.
For example, physicists strive to develop clocks of extreme accuracy so that any.
time or time interval can be precisely determined and compared. You may wonder whether such accuracy is actually needed or worth the effort. Here is one example of the worth: Without clocks of extreme accuracy, the Global Positioning System (GPS) that is now vital to worldwide navigation would be useless.

Links Between Homework Problems and Learning Objectives In WileyPLUS, every question and problem at the end of the chapter is linked to a learning objective, to answer the questions, “Why we should work on this problem? What is we supposed to learn from it?”By being explicit about a problem’s purpose, we must believe that a student might better transfer the learning objective to
other problems with a different wording but the same key idea. Such transference would help defeat the common trouble that a student learns to work a particular problem, but cannot then apply its key.
idea to a problem in a different setting.
The students have continued to be challenged by several key chapters and by.
spots in several other chapters and so, in this edition, it has been redesigned the chapters on Gauss’ Law and electric potential, which have proved to be tough going for most of the students. The presentations are now smoother and more direct to the key points.

In the quantum chapters, it has been expanded the coverage of the Schrödinger equation, including reflection of matter waves from a step potential.Spots in several other chapters and so, in this edition, it has been redesigned the chapters on Gauss’ Law and electric potential, which have proved to be tough going for most of the students. Also, there is now a module on Planck’s blackbody radiation. New Sample Problems and Homework Questions and Problems Sixteen new sample problems have been added to the chapters, written so as to spotlight some of the difficult areas for many students.Also about 250 problems and 50 questions have been added to the homework sections of the chapters. Some of these problems come from earlier editions of the book.

Much of physics is the study of things that move and video can often provide a
better representation than a static photo or figure. Online guidance Rather is a dynamic learning center stocked with many different learning aids, including just in time problem-solving tutorials, embedded reading quizzes to encourage reading, animated figures, hundreds of sample problems, loads of simulations and demonstrations, and over a lot of videos.
ranging from math reviews to mini-lectures to examples. For this 10th edition of this book, answers of the exercise problem can be found on net and a hint is provided in the book too. It will be helpful to you.

So guys that's all in this post. If you have any query related to this book or want to suggest to post a book, please email me or comment in the comment box. I will surely try to do my best to resolve your query. Till then keep practicing regularly and lead yourself towards excellence and success.

Mechanics 2 | Cengage Learning

Hello Everyone ,
This post is about the Cengage Magnetism and Electromagnetic Induction.

Overview : 

Physics for Joint Entrance Examination JEE (Advanced): Magnetism and Electromagnetic Induction, a Cengage Learning Exam Crack Series&trade product, is designed to help aspiring engineers focus on the subject of physics from two standpoints: 


 1. To develop their caliber, aptitude, and attitude for the engineering field and profession. 

 2. To strengthen their grasp and understanding of the concepts of the subjects of study and their applicability at the grassroots level. Each book in this series approaches the subject in a very conceptual and coherent manner. While its illustrative and solved examples will facilitate easy mastering of the concepts and their applications, an array of solved problems will expose the students to the variety and nature of questions that they can expect to face in the examination. The coverage and features of this series of books make it highly useful for all those preparing for JEE (Advanced) and aspiring to become engineers. 

Table Of Content : 

  • Chapter 1: Magnetic Field and Magnetic Forces 
  • Chapter 2: Sources of Magnetic Field 
  • Chapter 3: Electromagnetic Induction 
  • Chapter 4: Inductance 
  • Chapter 5: Alternating Current Miscellaneous Assignments Answers and Solutions

Concepts of Physics | HC Verma | IIT BOOKS


In this post we will talk about "HC VERMA VOL-1". This book is the game changer for the students who does not like to study physics or whose who are weak in physics.

ABOUT THE AUTHOR:

HC Verma sir, he is a retired professor and nuclear physics researcher at  IIT KANPUR. And of course the author of this master book. He is the co-founder of social initiative "SHIKSHA SOPAN" who works for the betterment in field of education for the economically weak but talented students living nearby IIT kanpur campus. Before coming to IIT Kanpur he was a lecturer at "PUNE SCIENCE COLLEGE" and worked there for 15 years. Currently he is working to introduce more good books to make some difficult chapters such as- electrostatics, magnetism easier for the students.

ABOUT THE BOOK:

HC Verma
This book is excellent in terms of both theoritical and numerical point. This book has deeply explained theory and a lot of real life illustrations to make the topic easier to understood. Apart from this, subjective, objective, very short, and short type questions are also given. Language used in this book is simpler and quite easier to understand. The book presents a calculus based physics course which makes free use of algebra, trigonometry and co-ordinate geometry. Almost no knowledge of physics is a prerequisite. This book will give you the attempt to start each topic from the zero level. But a receptive mind is all that is needed to use this book.
The book has various kind of problems adapted from real life situations. So that the student can more focus on the concept instead of mugging formulas. You will find the "ROPE AND MONKEY PROBLEMS" a lot interesting while dealing with them. Focusing on some chapters such as - kinematics, newton's law of motion, thermodynamics, fluid mechanics is recommended, as they are slightly difficult to understood as comparison with other chapters of this book.
So friends, that's all about this book. Hope you like the article. For any query please contact through contact us box or comment.
I will try to answer it as soon as I can.
