# Elastic Potential Energy Calculator

Enter the spring force constant and the stretch length of the spring/material to calculate spring potential energy.

## Elastic Potential Energy Formula

The following equation is used to calculate the potential energy of and elastic object, most often referred to as a spring.

U = 0.5 * k * y^2

• Where U is the potential energy in Joules
• k is the spring constant (N/m)
• and y is the distance the spring or object is stretched.

It can be seen from the equation above that the potential energy is linearly correlated with the spring constant and to exponentially to the distance it is stretched. This equation was formulated through the laws of potential energy as well as the law of elastic objects that indicates a spring constant.
