## Question:

If a spring is compressed 2.0 cm from its equilibrium position and the uncompressed an addition 4.0 cm, how much more work is done in the second compression than in the first?

## Potential Energy:

A mechanical quantity that describes the energy poses by the body with some displacement or at height is known as potential energy. Its measurable unit is Joule. The potential energy of spring is half of the product of spring constant and square of displacement.
