How it works

Fill in the 2 fields above and Coefficient of Friction Calculator calculates the result instantly, recalculating as you change any value. It applies the formula μ = F_friction / F_normal. The math runs locally in your browser — nothing is sent to a server.

Formula

μ = F_friction / F_normal

Examples

  • Friction force 40 N, Normal force 100 N → Coefficient (μ): 0.4
