Friction Calculator

Calculate the frictional force (static or kinetic) between two surfaces. Simply input the coefficient of friction and the normal force acting on the object.

How to Use

  1. 1

    Enter Coefficient of Friction

    Input the coefficient (μ) between the two surfaces. This is a dimensionless number, typically between 0 and 1.

  2. 2

    Enter Normal Force

    Input the normal force in Newtons. For an object resting on a flat surface, this is equal to its weight (mass × gravity).

  3. 3

    Calculate

    Click calculate to find the total force of friction resisting the motion.
