Friction ( \(FRICT\) ) is the mechanical resistance to the relative movement of two surfaces. There are two main types of friction; static friction and dynamic friction. Typically static friction is greater than dynamic friction.
\( f =\mu F_n \;\)
\(f\) = friction
\(\mu\) (Greek symbol mu) = friction coefficient
\(F_n\) = normal force
