Friction Force Calculator

Find static or kinetic friction force.

CALCULATE

Formulas

f = μ × N

f = friction force, μ = friction coefficient, N = normal force

Friction Coefficients

Static (starting) > Kinetic (sliding). Rubber on dry concrete: 0.6-0.8. Steel on steel: 0.5-0.8. Ice on ice: 0.03. Teflon: 0.04. Wood on wood: 0.25-0.5.
