is one of the physical quantities as it is proportional to the mass of the object. The ability of the body to

exert a push or a pull against the natural forces like gravity identifies as to what kind of energy is it.

When an object is at rest, the body is said to possess potential energy. In another case, when the object

is in motion, then it is said to possess kinetic energy.

a. A freely falling object eventually stops on reaching the ground. What happens to its kinetic

energy?

b. Define S.I unit of energy.
