Calculate the frictional force acting on an object, including both static and kinetic friction. This calculator uses the coefficient of friction and normal force to determine the magnitude of the friction force.
Enter your values below
μs (static) or μk (kinetic) depending on situation
Force perpendicular to the contact surface
Static friction prevents motion; kinetic friction opposes sliding
How this calculator works
Friction force equals the coefficient of friction times the normal force. Use μs for static and μk for kinetic friction.
