Kinetic or dynamic friction, Mechanical Engineering

Kinetic (Dynamic) Friction:

When applied force exceeds limiting friction the body starts moving over the other body and the friction of resistance experienced by the body at the time of moving. This is called as law of Dynamic or kinetic friction.

Or

It is friction experienced by body when in motion. It is of two types;

1. Sliding Friction

2. Rolling Friction

Sliding Friction: It is friction which is experienced by the body, when it slides over another body.

Rolling Friction It is friction experienced by the body, when it rolls over the other.
