Elastic Potential Energy Calculator

Find the energy stored in a stretched/compressed spring.

Elastic PE (J) 1

Formula: PE = ½ k x²

Step-by-step with your numbers:

1. Values used:

2. Spring constant = 200 N/m

3. Displacement = 0.1

5. Elastic PE = 1J

Did we solve your problem today?

A spring stores energy when stretched or compressed.

The math behind it

PE = ½ × spring constant × displacement².

k 200 N/m, x 0.1 m → 1 J.

Hooke's law?

The force is F = kx; the stored energy is the area under that line, ½kx².
