Friction Calculator

Use this friction calculator to quickly determine the frictional force between surfaces based on their material and the applied normal force.

Use this calculator to compute the frictional force exerted when an object moves across a surface. The calculator uses the formula: F_f = μN, where F_f is the frictional force, μ is the coefficient of friction, and N is the normal force.

How to Use the Friction Calculator

Enter the normal force (N), which must be in newtons.
Enter the coefficient of friction (μ), which is a unitless value.
Click the “Calculate” button to see the frictional force.

How the Friction Calculator Works

The calculator multiplies the normal force by the coefficient of friction to yield the frictional force. It’s based on the equation derived from the fundamental principle of friction.

Limitations of the Calculator

The calculator assumes a constant coefficient of friction and does not take into account factors that can affect frictional force, such as temperature, surface area, or velocity of movement. It is intended for educational and informational purposes only.
