Define limiting and kinetic friction

Solution (By Examveda Team)

The force of friction between two surfaces when the body is in static condition is called static friction and is equal to the applied force. The maximum value of static friction is called limiting friction.
The force of friction when the block is sliding is called kinetic or dynamic friction. For a limited speed, the kinetic friction remains constant throughout the motion.
Kinetic friction is always less than limiting friction.
