The dynamic friction is the friction experienced by a body, when the body

A is in motion
B is at rest
C just begins to slide over the surface of the other body
D none of the mentioned

Correct Answer: is in motion

The friction, experienced by a body, when at rest, is known as static friction. The friction, experienced by a body, when in motion, is known as dynamic friction. The maximum frictional force, which comes into play, when a body just begins to slide over the surface of the other body, is known as limiting friction.
