Graph Between Applied Force and Force of Friction
Category : JEE Main & Advanced
(1) Part OA of the curve represents static friction \[({{F}_{s}})\]. Its value increases linearly with the applied force
(2) At point A the static friction is maximum. This represent limiting friction \[({{F}_{l}})\].
(3) Beyond A, the force of friction is seen to decrease slightly. The portion BC of the curve represents the kinetic friction \[({{F}_{k}})\].
(4) As the portion BC of the curve is parallel to x-axis therefore kinetic friction does not change with the applied force, it remains constant, whatever be the applied force.
