Friction is the force that combats relative motion between the two surface that come in contact. Friction always act in the opposite direction of the applied force.
Types of Friction :-
1. Static Friction- The opposite force that comes into play when one body tends to move over the another surface, but the actual motion has not yet stated.
2. “Static friction is the friction that is present when two bodies are static. This kind of friction can stop from moving on a path.
Dynamic friction- The opposing for that comes into play when one body in actually moving over the surface of another body. Dynamic friction may be of two types.
1. Rolling friction- The opposing force that comes into play when one body is actually rolling overthe surface of another body.
For example, hockey / cricket ball is hit.
2. Sliding firction- The opposing force that comes into play when one body is actually sliding over the surface of the other body.
For example-Ice sketing.
