Hooke's Law Calculator

Enter a spring constant and displacement to calculate the restoring force and stored elastic potential energy.

Restoring force

10.000 N

Elastic potential energy

0.250 J

Uses Hooke's Law, F = kx, valid within a spring's elastic limit. Stored energy uses PE = ½kx².

How to use this tool

  1. 1Enter the spring constant k in N/m.
  2. 2Enter the displacement from equilibrium in meters.
  3. 3See the force and stored energy.

Frequently asked questions

When does Hooke's Law stop applying?+

It only holds within a spring's elastic limit — stretch or compress it too far and the relationship between force and displacement stops being linear.
