How to use the Elastic Potential Energy Calculator

The Elastic Potential Energy Calculator works out your elastic potential energy in an instant. Enter spring constant and displacement and the result updates as you type — it is free, needs no sign-up, and runs entirely in your browser so your figures stay private.

  1. Enter the spring constant.
  2. Enter the displacement.
  3. Read off your elastic potential energy — the calculator updates automatically, with no button to press.

Formula

The Elastic Potential Energy Calculator uses the formula:

Elastic potential energy = 0.5 × Spring constant × Displacement ^ 2

Worked example

For example, with spring constant of 200 N/m and displacement of 0.1 m, the elastic potential energy is 1.0000.

Inputs used
Spring constant 200 N/m
Displacement 0.1 m
Results
Elastic potential energy 1.0000

Results are estimates for educational use, not professional advice.

Key terms explained

Potential energy
Stored energy due to an object's position, equal to mass × gravity × height.

Frequently asked questions

It is energy stored in a stretched or compressed spring: E = ½ × k × x². A 200 N/m spring at 0.1 m stores 1 joule.

It measures stiffness in newtons per metre; a higher value means a stiffer spring that stores more energy for the same stretch.

Energy rises with the square of displacement, so doubling the stretch stores four times the energy.

Springs, bows, trampolines and any elastic system that stores and releases energy.

The Elastic Potential Energy Calculator uses the formula: Elastic potential energy = 0.5 × Spring constant × Displacement ^ 2. For example, with spring constant of 200 N/m and displacement of 0.1 m, the elastic potential energy is 1.0000.

Enter the spring constant. Enter the displacement. Read off your elastic potential energy — the calculator updates automatically, with no button to press.
