When a body move over another body then created between them a dynamic fraction.

Why, dynamic because during motion friction force acts is slightly lesser than limiting friction due to inertia therefore it is termed as dynamic friction.

Yes that is dynamic friction, because the body is in motion that's why that has dynamic friction.

As here mentioned that type of the motion of the body is known to us, so the body is in motion (dynamic condition) for this reason only it will come across dynamic friction.

Friction due to motion is known as dynamic friction.

The friction has two types:

1. Dynamic friction.

2. Sliding friction.

Dynamic friction applied on the body in motion.

Sliding friction applied on the body in rest.

Friction due to the motion.

Thank you too much for this, really before I did not understand it. Can you please give me explanation for other options?

In nature friction is only three types are available in air we called air resistance in liquids we called -viscosity in Solids we called friction. According to discussion friction basically two types 1st static friction and 2nd dynamic friction according to discussion dynamic means motion (any object which can observed as motion) and friction is surface property which can exert when two or more then bodies are contact and also known motion opposing force.

And dynamic friction is define when body is experienced motion then those force exert on body as a retarding parameter or to reduce the motion of body then body experienced dynamic friction.

If a body is in motion it experience a friction with the surface is called kinetic friction, if dynamic friction=kinetic friction then I agree that is dynamic friction.
