There are two variables required to calculate elastic potential energy:
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.
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:
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.
The spring constant 𝑘 is a measure of the stiffness of the spring and is usually provided by the manufacturer. If it's not provided, you can calculate it by dividing the force applied to the spring by the displacement it causes.
This calculator is specifically designed for systems that follow Hooke's Law, where the force is directly proportional to the displacement. It may not be accurate for materials that exhibit nonlinear elastic behavior.
