Hooke's Law Calculator
Use Hooke's law to find a spring's force, spring constant or stretch, plus the elastic energy it stores.
Spring force
10 N
- Spring force (kN)
- 0.01 kN
- Spring force (lbf)
- 2.24809 lbf
- Spring force (kgf)
- 1.01972 kgf
- Elastic potential energy (½kx²)
- 0.25 J
Show the work
Stretch or compression in m
m = cm × 0.01
5 × 0.01 = 0.05 m
Spring force from the two you know
F = k × x
200 × 0.05 = 10 N
How it works
F = kx (force magnitude); elastic potential energy = ½kx²
