 Friction coefficient, abbreviated as \(\mu\), also called coefficient of friction, a dimensionless number, is the ratio between two contacting surfaces and the frictional force that resists the normal force of the object.


Friction coefficient formula

\(\large{  \mu =   \frac{F_a}{F_n}  }\) 


 Units English Metric
\(\large{ \mu }\)  (Greek symbol mu) = friction coefficient \(\large{ dimensionless }\)
\(\large{ F_a }\) = applied force \(\large{ lbf }\) \(\large{N}\) 
\(\large{ F_a }\) = normal force \(\large{ lbf }\) \(\large{N}\)
