Friction Calculator

Find the friction force from the coefficient and normal force.

Calculated Output

Friction force (N) 40

Formula: F = μ · N

Step-by-Step Breakdown

1. Values used:

2. Friction coefficient μ = 0.4

3. Normal force = 100 N

5. Friction force = Friction coefficient μ x Normal force = 0.4 x 100 = 40N

Did this calculator solve your problem today?

The math behind it

F = μ·N, where μ is the friction coefficient and N is the normal force.

μ = 0.4, N = 100 N → friction 40 N.

Static vs kinetic friction?

Static (before sliding) usually has a higher coefficient than kinetic (while sliding).
