Question

How does the energy of an object change when it performs work or work is done on it?

Answer 1

Explanation

1. Work changes the amount of mechanical and internal energy possessed by objects.
2. When work is done on a system or object, energy is added to it.
3. When work is done by a system it gives some of its energy to object, and when work is done by a object it gives some of its energy to system.

Hence, When an object does work, it loses its energy or when work is done on an object, the object gains energy.
