Answers (1)

best_answer

Frictional force-

The force which opposes the relative motion between two surfaces in contact is known as friction.

  • Friction is a force that comes into play when two surfaces come in contact with each other.

  • Friction acts on the surface of contact of both the bodies.

  • All types of surfaces like solid, liquid, and air offer the force of friction.

  • The friction force always applies in the opposite direction of relative movement.

Example of friction force-

1. After applying brakes to a moving bike, the surface of brakes offers friction to the surface of the moving wheel and the bicycle stops because of the force of friction.

2. A moving wheel on the ground stops after covering a certain distance because the surface of the ground offers opposite direction friction to the surface of the wheel in motion.
