Name the form of energy which a body may possess even when it is not in motion. Give an example to support your answer.

What do you understand by the kinetic energy of a body?

A body of mass m is moving with a uniform velocity u. A force is applied on the body due to which its velocity increases from u to v. How much work is being done by the force?

A light mass and a heavy mass have equal momentum. Which will have more kinetic energy?
