Concept Explanation
 

Elastic Potential Energy

Elastic Potential Energy

This is a kind of potential energy which is due to a change in the shape of  body. The change in shape of a body can be brought about by stretching, compressing, bending and twisting the body. Some work has to be done to change the shape of a body. This work gets stored in the deformed body in the form of elastic potential energy.

For example, the energy stored in a stretched rubber band or a spring is elastic potential energy and is equal to the work done in stretching the rubber band or spring. When this deformed body is released, it attains its original shape and the potential energy is converted into some other form, usually in kinetic energy. Elastic potential energy is never negative whether due to extension or to compression.
