Static Friction Coefficientstatic friction coefficient

Static friction coefficient ( \(\mu_s\) ) (dimensionless number) (also called coefficient of static friction) is the amount of force that resists motion that is on the verge of motion.

Static Friction Coefficient formula

\( \mu_s =   \frac {f_s}{F_n}\)          \( static \; friction \; coefficient  \;=\;   \frac { static \; friction }{ normal \; force }\) 


\(\mu_s\) (Greek symbol mu) = static friction coefficient

\(f_s\) = static friction

\(F_n\) = normal force
