Friction force calculator

Calculate friction force or limit with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Use friction force or limit to compare changes to your inputs. The method and limits below explain the scope.

Examples

Friction force or limit (N)

a × b

Symbols and units
a
Friction coefficient
b
Normal force (N)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • Use a kinetic coefficient for sliding force or a static coefficient for the maximum static limit, not automatic static force.
