In Ques 1 the force of dynamic friction is.

(A) : It is easier to maintain the motion than to start it on rough surface . (R) : Dynamic/kinetic friction is less than the force of limiting friction .

Choose the correct options – (1) Friction always opposes the motion (2) Friction may opposes the motion (3) If the applied force is increased the force of static friction remains constant. (4) If the applied force is increased the force of static friction also increases upto limiting friction.

The Force of friction is _______.

Assertion : The value of dynamic friction is less than the limiting friction. Reason : Once the motion has started, the inertia of rest has been overcome.
