Explain the types of frictions in short.

Frictional force is of three types:–

I. Static Friction – It is the frictional force acting on a body when the body has not started moving yet and is at rest, also this friction is equal to the amount of force applied on the body and is variable to a certain limit.


II. Sliding Friction – It is the friction acting on the body when it is in motion and this friction is constant and is always less than the maximum value of static friction.


III. Rolling Friction – It is the constant friction acting on the body through wheels, it is the least amount of friction of all and is only applied when the body is moving.
