## Hooke's Law for Springs
A spring produces a restoring force proportional to its displacement from equilibrium.
### Formulas
**F = k x** (Hooke's law)
**U = 0.5 k x^2** (elastic potential energy)
where k is the spring constant, x is the displacement, F is the resulting force, and U is the stored energy. This holds as long as the spring remains in its linear elastic range.

Esempio Risolto
A spring with k = 5 N/mm compressed by 20 mm.
- F = 5 x 20 = 100 N
- U = 0.5 x 5 x 20^2 = 0.5 x 5 x 400 = 1000 N-mm = 1.0 J
