Work, energy and power is one of the important chapter of class 11 physics which contain more than 3 most important and most repeated questions for neb exam.
Some important questions of Work, Energy and Power
What is Work?
A work is said to be done if the force applied on a body displaces it in the direction of force.
What is Energy?
It is defined as the capacity of doing work. There are two types of mechanical energy:
- Potential Energy : It is the energy possessed by a body due to its position from the ground.
- Kinetic Energy: It is defined as the energy possessed by a body when it is in motion.

What is Work - Energy theorem?
It states that work done on a body is equal to increase in kinetic energy of the body.
What is Principle of conservation of energy?
It states that energy can neither be created nor be destroyed but it simply changes its form from one to another.

What is Collision?
It is the mutual interaction between the two particles due to which their kinetic energy or momentum or path change. There are two types of collision:
Elastic collision: The collision in which total linear momentum and total kinetic energy of the system are conserved is called elastic collision. Example: collision between gas molecule.
Properties of elastic collision:
- Total linear momentum is conserved.
- Total kinetic energy is conserved.
