Our subject matter experts have complete knowledge of the CBSE guidelines and have aligned the solutions accordingly. We have kept the language of the solutions easy to understand and have included explanations wherever necessary so that you do not have to read the chapter again and again. These NCERT solutions will act as a revision guide for you at the time of exams.

## Important Topics for NCERT Solutions for Class 11 Physics Chapter 6

The NCERT Solutions for Class 11 Physics Chapter 7 Work, Energy, and Power have around 11 sub-topics namely work done, work-energy theorem, collisions, kinetic energy, conservation of mechanical energy, potential energy in a spring, the law of conservation of energy and power. In this chapter, you will also learn about Scalar Product which is an important concept for entrance exams like JEE and NEET.

In the second section of the chapter, you will derive the formula for work done and kinetic energy. You must note that work done is defined as the displacement caused in an object due to force. Also, if the kinetic energy of an object changes due to force applied onto it, it is also called work done.

Then, you will learn about work done by a variable force and hence the changed work-energy theorem related to it. Both these topics include the derivation of the formulae that are very important from the exam point of view. Then comes the topic of potential energy which the energy possessed by any object at rest.

This chapter also deals with the Law of Conservation of Energy and various concepts related to power. Apart from the main concepts, the lesson also deals with various formulae, calculations, and problems which are related to the concepts that you are going to practice in the NCERT exercises. There are 13 solved examples in the chapter that will help you grasp the topics in a better way.

Our expert team has put in a lot of research and effort into coming up with the NCERT solutions for class 11 physics chapter 7 to help you study, evaluate and grasp the concepts to the best extent possible. Our solutions will help you gain top marks in your CBSE Class 11 Physics Exams.
