Friction Calculator

Typical values: ice on steel ≈ 0.03, wood on wood ≈ 0.3–0.5, rubber on dry concrete ≈ 0.6–1.0.

Normal force (= weight)98.0665 N
Friction force (max static / kinetic)49.0332 N

A 10 kg box (weight 98.07 N) with μ = 0.5 experiences up to 49.03 N of friction — you must push harder than that to start it sliding.

F = μ × N; N = m × g on a horizontal surface, g = 9.80665 m/s² · Powered by CalcHub — Friction Calculator
