Formula

## 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.

  1. 01F = 5 x 20 = 100 N
  2. 02U = 0.5 x 5 x 20^2 = 0.5 x 5 x 400 = 1000 N-mm = 1.0 J
