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.
- “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.
