Friction Calculator
Force and Coefficient
Calculate friction force and coefficient of friction for various surfaces using F = μN.
Friction Parameters
Static friction coefficient (0-2 typical range)
kg
°
0° = horizontal, 90° = vertical
Friction Formula
F = μN
where: F = friction force, μ = coefficient, N = normal force
Note
Static friction coefficients are typically higher than kinetic (sliding) friction. Values shown are for static friction.
About Friction
Friction is a force that opposes motion between surfaces in contact. It depends on the normal force and the coefficient of friction.
- Static friction prevents motion
- Kinetic friction opposes sliding
- Proportional to normal force
Applications
- Brake system design
- Tire and road interaction
- Machine component design
- Sports equipment
- Material selection
