Hooke’s law calculator
For a spring used within its elastic range, the magnitude of the restoring force is proportional to the extension or compression.
Formula usedF = kx

Two worked examples
Example 2
If 30 N produces an extension of 12 cm, the spring constant is 250 N/m.
Good to knowThe calculator uses force magnitude. The restoring force itself points opposite to the displacement.
