Friction Force Calculator
Compute friction force F_f = μ·N from coefficient and normal force.
Input Data
Coefficient
Normal Force N

Results
F_f = μ·N.
30N

100N
At a glance:F_f = μ·N (kinetic or static max). Complements normal-force and coefficient-of-friction.
Formula
F_f = μ·N.
$$f = \mu N, \quad f_{s,\max} = \mu_s N, \quad f_k = \mu_k N, \quad N = mg\cos\theta$$How to Use
- Enter μ and normal force.
- The tool returns the friction force.
Case Studies
μ=0.3, N=100
F_f = 30 N.
FAQ
Static vs kinetic?
Static μ_s > kinetic μ_k; static caps the applied force before motion.
