kinetic friction coefficientKinetic 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:

 Units English Metric
\(\large{ \mu_k }\)  (Greek symbol mu) = kinetic friction coefficient \(\large{ dimensionless }\)
\(\large{ f_k }\) = kinetic friction \(\large{ lbf }\) \(\large{N}\) 
\(\large{ F_n }\) = normal force \(\large{ lbf }\) \(\large{N}\)
