Does friction always oppose the motion?

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.

Assertion : Friction always opposes the motion. Reason : Whenever one surface moves or tries to move over another surface, the force of friction starts acting on the surfaces.

Assertion: Frictional force is the component of contact force parallel to the surface. Reason: Friction force always opposes the motion of a body.

Assertion : The force of tension on a body always act away from the body. Reason: Friction force always opposes the motion of a body.

Viscous force is somewhat like friction as it opposes the motion and is non-conservative but not exactly so because

(A) : Force of friction applied by ground on the wheels of a bicycle is always in the direction of motion of the bicycle . (R) : Force of friction always opposes the relative motion between the surfaces in contact .

Friction is always
