Calculate static and kinetic friction forces for common material pairs

Friction Calculator

Calculate static and kinetic friction forces for common material pairs.

Max Static Friction (Fs)370.00 N
Kinetic Friction (Fk)285.00 N

Coefficient Summary

μs = 0.74μk = 0.57Ratio: 0.77

Formula

Fs_max = μs · N = 0.74 × 500.00 = 370.00 N
Fk = μk · N = 0.57 × 500.00 = 285.00 N
Static friction opposes impending motion; kinetic friction acts during sliding.
