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

\( kinetic \; friction \; coefficient   \;=\;   \frac {   kinetic \; friction }  {   normal \; force  }\)

\( \mu_k =   \frac {f_k}{F_n}\) 

Where:

\(\mu_k\) (Greek symbol mu) = kinetic friction coefficient

\(f_k\) = kinetic friction

\(F_n\) = normal force
