Kinetic Friction

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Kinetic friction is the force opposing two objects rubbing together that are moving relative to each other.

formula

\(f_k = \mu_k F_n \)

Where:

\(f_k \) = kinetic friction

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

\(F_n\) = normal force

Solve for:

\(\mu _k = \frac {f_k}{F_n} \)

\(F_n = \frac {f_k}{\mu_k}\)
