Kinetic Friction Coefficient

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

Kinetic Friction Coefficient FORMULA

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

Where:

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

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

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