Elastic Potential Energy Calculator

How do you Calculate Elastic Potential Energy?

There are two variables required to calculate elastic potential energy:

• Spring force constant


• Spring stretch length

You can then use this formula to calculate the elastic potential energy: Where:

• EPE = Elastic Potential Energy


• k = Spring force constant


• SL = Spring Length, whether compressed or stretched out

Understanding Your Results

Your result will be a single number that is displayed in joules by default. This is the amount of potential energy that the object has based on your entries. It can easily be converted into other units of energy measurement by selecting another option from the dropdown menu next to the result.

How to Use the Elastic Potential Energy Tool

Our tool is very easy and simple to use and can get you an answer in less than a minute. The steps required to use this tool include:

1. Enter the spring force constant.


2. Enter the spring stretch length, ensuring you select the proper unit of length measurement if inches is not the correct for you.


3. Hit calculate and get the elastic potential energy instantly!

Example Calculation

Let's say you have a tiny spring that you want to study closer. It is a total of 4 inches long and has a spring force constant of 20 newtons per meter. You can use this tool to find the elastic potential energy, so we will enter 20 into the first field and 4 into the second field.

We are now ready to hit calculate and get our answer which is .1032 joules. If we need the answer in foot-pounds instead we can choose that unit from the dropdown and the answer is automatically converted to .0761 foot-pounds.
