# Physics Revision Notes for Class 11 Chapter 6 Work Energy and Power

The class 11 physics revision notes chapter 6 work, energy and power bring you the excitement of understanding all the need to know things related to the very important concept in physics which is work, energy, and power.

## CBSE Notes Class 11 Physics Chapter 6 Work, Energy and Power

We are aware of the definition of this chapter such as:

• When a force acts upon an object to cause a displacement of the object, it is said that work was done upon the object
• Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms
• Power is the rate at which work is done. It is the work/time ratio

Students will get all your doubts clarified on important terms such as kinetic energy, potential energy, and work-energy theorem. The most important concept that is the law of conservation of energy is explained here in a beautiful manner for their convenience. Students will discover the varieties of collision in one and two dimensions and along with that, they will also get to know the energy associated with important phenomena such as work done by the human heart etc.

## Frequently asked Questions on CBSE Class 11 Physics Notes Chapter 6: Work Energy and Power

Q1

### What is the ‘Law of conservation of energy’?

The law of conservation of energy states that the amount of energy is neither created nor destroyed.

Q2

### What is ‘Work’?

The measure of energy transfer that occurs when an object is moved over a distance by an external force is known as ‘Work’.

Q3

### What is the definition of ‘Power’?

Power can be defined as the rate of doing work.
