Define coefficient of Kinetic friction. Give the necessary formulae.

Assertion : Static friction is a self-adjusting force upto its limit mu_(s)N "where" mu_(s) is the coefficient of static friction. Reason: One can use the equation f_(s)=mu_(s)N only when the maximum value of static friction comes into play
