# Elastic Potential Energy

`U = 1/2 * k * d^2`

Calculator of the elastic potential energy of a spring.

Calculator of the elastic potential energy of a spring.

**Enter 'x' in the field to be calculated.**This tool calculates the potential elastic energy of a spring with one end fixed and the other end is in extension or compression. The calculation formula used is as follows:

`U = 1/2 * k * d^2`

d: spring extension or compression in meter

k: spring constant in N/m

U: Joule spring elastic potential energy

Special case

When d = 0, the spring is neither extended nor compressed, ie it is in its normal state: the elastic potential energy is zero in this case.
