Can frictional force be greater than applied force?

The force opposing the motion of a body is called frictional force. It's value depends on the co-efficient of friction or in other words how rough the surface is. read more

No, frictional force cannot be greater than applied force. as friction force is a self adjusting force so it sets its value equal to the value of applied force. maximum value that can frictional force attain to oppose applied force is called limiting friction. read more

Since there is no other horizontal force acting on the rock, the rock accelerates to the left. There you have a case where the applied force is zero but the friction force is nonzero. However, in the"normal" case, where the platform isn't accelerating, the friction force can't ever be greater than the applied force. read more
