WebOct 31, 2006 · where is the coefficient of static friction at maximum at the contact surface. Kinetic friction : However, the friction acting on a resting block is less than until the block starts to move. For example, once the body starts to move over the rough surface, the friction would decrease slightly to a value known as kinetic friction .
