Calcolatrice Forza di Attrito — Formula
## Friction Force
Friction opposes relative motion between two surfaces in contact.
### Formula
**f = mu * N**
where mu is the coefficient of friction (static or kinetic) and N is the normal force perpendicular to the surface.

Esempio Risolto
A 10 kg box on a flat floor has a kinetic friction coefficient of 0.5.
- Normal force N = m * g = 10 * 9.81 = 98.1 N
- f = mu * N
- f = 0.5 * 98.1
- f = 49.05 N
