Friction Calculator
Estimate static or kinetic friction forces using μ and the normal force
Inputs
Friction force: F = μ · N, where N is the normal force. Static μ gives the maximum before motion; kinetic μ applies during motion.
Helps estimate effective weight components (N = mg·cosθ if you already computed mg).

How to Use the Result
- The static friction value is the threshold; any applied force greater than this causes motion.
- Kinetic friction is typically lower than static friction for the same surfaces.
- If you only know mass m, compute N = m · g · cosθ first, then plug it into the calculator.
