Define coefficient of kinetic friction.

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following four responses Assertion Static friction acting on a body is always greater than the kinetic friction acting on this body. Reason Coefficient of static friction is more than the coefficient of kinetic friction.
