Kinetic Friction Coefficient

Written by Jerry Ratzlaff. Posted in Dimensionless Numbers

kinetic friction coefficientKinetic friction coefficient is a dimensionless number, the amount of force that resists motion at a constant velocity.

FORMULA

\( \mu_k =   \frac {f_k}{F_n}\) 

Where:

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

\(f_k\) = kinetic friction

\(F_n\) = normal force
