Yes, smooth surfaces can still produce friction. Friction is caused by the resistance between two surfaces when they are in contact with each other, not only by the texture of the surfaces. Smooth surfaces can still generate friction, although the amount of friction may be lower compared to rough surfaces.

A smooth surface will produce the least amount of friction compared to a rough surface. Friction is caused by the resistance when two surfaces slide against each other, and smoother surfaces have fewer microscopic irregularities that create friction. The coefficient of friction is lower for smooth surfaces.
Two rough surfaces in contact will produce more heat due to increased friction compared to two smooth surfaces or a smooth and rough surface. Adding oil between two surfaces will reduce friction and heat generation.
Rough surfaces typically produce more friction compared to smooth surfaces. This is due to the increased contact points between the surfaces, resulting in more resistance to motion.
A rough, bumpy surface typically produces more friction compared to a smooth surface. The irregularities on the rough surface create more contact points between surfaces, leading to increased resistance and friction during movement.
The force is greater on a rough surface compared to a smooth surface, due to the increased friction between the surfaces. The rough surface provides more resistance to motion, requiring more force to overcome the friction.
