Yes, friction still exists between two surfaces even if one of them is moving. Friction is a force that resists the relative motion or the tendency of motion between two surfaces in contact. There are two types of friction: static friction and kinetic friction.
Static friction acts between two surfaces that are not yet in motion relative to each other. It prevents the object from moving when a force is applied to it. Kinetic friction, on the other hand, occurs when two surfaces are sliding or moving relative to each other. It opposes the motion between the surfaces.
When one surface is moving relative to another, kinetic friction comes into play. This frictional force opposes the motion and acts in the direction opposite to the velocity of the moving object. The magnitude of kinetic friction depends on factors such as the nature of the surfaces in contact, the normal force between the surfaces, and any other influencing factors.
So, even when one surface is moving, there can still be friction between the surfaces, resulting in a resistive force that affects the motion of the objects involved.
