The following statement is one of the laws of Dynamic friction

The magnitude of the kinetic friction bears a constant ratio to the normal reaction between two surfaces. The ratio being slightly less than that in the case of limiting friction

For moderate speeds the force of friction remains constant but decreases slightly with the increase of speed

The force of friction always acts in a direction opposite to that in which a body is moving
