Friction Force Calculator
Enter a mass, incline angle, and coefficient of friction to calculate the normal force and friction force.
How to use this tool
- 1Enter the object's mass.
- 2Enter the incline angle (0° for flat ground).
- 3Enter the coefficient of friction.
- 4See the normal force and friction force.
Frequently asked questions
Should I use the static or kinetic coefficient?+
Use the static coefficient to find the force needed to start motion, or the kinetic coefficient to find the friction force while already sliding — they're usually different values for the same surfaces.
