What is friction and it types
Asked by gauravsinghi39.8misj | 15 Jun, 2021, 05:20: PM

### When a body slides ( or rolls ) over a surface, a force starts acting on the body, in a direction opposite to the motion of the body, along the surface in contact. This is called the frictional force or the force of friction.There are three types of friction :1) Static friction- The friction that exists between the two surfaces in contact when there is relative motion between them is about to start is called static friction.2) Kinetic friction-The friction that exists between a surface sliding on another surface is called kinetic friction. 3) Rolling friction-When a body rolls on the the surface of another, the friction that exists between the surfaces is called static friction.
