The following statement is one of the laws of Dynamic friction

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

All of these

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

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
