Kinetic Friction Calculator

I want to calculate
Dynamic friction coefficient (μk) = N
Normal force (N) = N
Dynamic friction (Fk) = N
 

What is a Kinetic Friction Calculator?

A Kinetic Friction Calculator determines the force opposing motion between two surfaces in contact. It uses the formula:

Fk=μk⋅NF_

where:

  • Fk = Kinetic friction force
  • μk​ = Coefficient of kinetic friction
  • N = Normal force (usually N=mg, where mm m is mass and gg g is gravity)

Why use a Kinetic Friction Calculator?

  • To analyze motion resistance in physics and engineering.
  • To design efficient mechanical systems.
  • To study friction effects in sports, vehicles, and machinery.

How does it work?

  1. Input the coefficient of kinetic friction.
  2. Input the normal force (or mass and gravity).
  3. The calculator finds the kinetic friction force.

When is it used?

  • In physics experiments.
  • In mechanical and automotive engineering.
  • In sports science (e.g., analyzing sliding motion).
