Kinetic Friction Coefficient

Written by Jerry Ratzlaff on . Posted in Dimensionless Numbers

Kinetic friction coefficient, abbreviated as $$\mu_k$$, is a dimensionless number, also called coefficient of kinetic friction, is the amount of force that resists motion at a constant velocity

Formulas that use Kinetic Friction Coefficient

 $$\large{ \mu_k = \frac {f_k}{F_n} }$$

Where:

$$\large{ \mu_k }$$  (Greek symbol mu) = kinetic friction coefficient

$$\large{ f_k }$$ = kinetic friction

$$\large{ F_n }$$ = normal force
