Kinetic Friction Coefficient

Kinetic friction coefficient, abbreviated as \(\mu_k\), a 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
