Answer:
Coefficient of static friction is normally greater than coefficient of sliding friction which is also known as coefficient of kinetic friction.
Explanation:
Coefficient of friction can be seen as the cumulative effect of the irregularities that are on the surface of objects. When these interlocking get locked into one another a resistance arises to the motion of the object which is termed as friction. When an object is static these irregularities get more time to be interlocked as compared to when an object is in motion thus the coefficient of static friction is more than the coefficient of sliding friction.
