Elastic Potential Energy Calculator

If you want to determine the spring's potential energy when it's compressed or stretched, you can use our elastic potential energy calculator.

The energy stored as a result of implementing force to deform or configuration of an elastic object is known as the elastic potential energy. This eclectic energy usually occurs when an elastic object like a spring is stretched, compressed, or deformed in any condition. This elastic potential energy is released when it comes back to its initial state. At the same time, the elastic potential energy remains positive always. The SI unit used for the potential energy is Joules (J).


Formula of Elastic Potential Energy Calculator

To determine the potential energy in an elastic object, you can use our calculator or the formula listed below:

U = ½kΔx²


k = spring constant. SI unit is Newton/meter

Δx = deformation derived in meters (m)

U = elastic potential energy measured in Joules (J).


To calculate the price elasticity of demand, you can use our Price Elasticity Of Demand Calculator.


To understand how to find the spring potential energy, let us have an example below:

Suppose a spring stretched by weighting it, whereas the spring constant is 80N/m, and the 0.15m of deformation occurred in spring. Find the potential energy stored by a spring.

Given data

Spring constant = 80 N/m
Deformation occur = Δx = 0.15m

To Find

The potential energy stored by a spring = ?


To find the potential energy stored by a spring, let us use the formula listed below:

U = ½kΔx²

Putting values in the formula:

U = (0.5) * (80) * (0.15)²
U = 0.9 J
