Friction
Friction
Two bodies placed in contact can exert forces parallel to the surfaces in contact. Force acting between the surfaces of two objects is called the force of friction. Force of friction always acts in the opposite direction of the movement of object. Force of friction is acting over all the moving objects. For example:
1. A moving ball stops after going to a certain distance. This happens because of force of friction between the surface of ground and the surface of ball.
2. A moving boat stops after some distance because of friction between the surface of water and the surface of boat.
Since force of friction comes into action only after interaction between two objects, thus, it is a type of contact force.
