The friction experienced by a body in motion is known as dynamic friction. The body enters into motion when the force acting on it is greater than the limiting friction.

Dynamic friction is the type of friction that now exists between the contact surfaces. The limiting static friction is always less than the dynamic friction.

Why not it should be a rolling friction?

When the body is in motion the friction is called dynamic friction and when the body is in rest the friction is called static friction.

The motion of the body from one place to another is called dynamic motion.

When body is in motion then always act dynamic friction opposite direction to the motion.

Kinetic friction is the opposing force that comes into play when one body is actually moving over the surface of another body.
