Plane surface with negligible friction.
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.
A smooth, slippery surface like ice or Teflon typically has the least amount of friction. This is because these surfaces have very low coefficients of friction, allowing objects to slide easily with minimal resistance.
Rolling friction produces the least amount of friction compared to other types of friction like sliding or static friction. This is because rolling friction involves an object rolling smoothly over a surface with minimal resistance.
Ceramic bearings typically have the least coefficient of friction compared to steel or other materials. Their smooth surface, hardness, and resistance to wear make them ideal for reducing friction in various applications.
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.

Surface friction ALWAYS point parallel to the surface and opposite motion. There must be a normal force for there to be friction
friction
the rougher the surface is, the more friction there will be
the smoother a surface is, the less friction it produces.
It is difficult to strike a match on a smooth surface because the friction needed to ignite the match head is lacking. Matchboxes and striker surfaces are designed to provide enough friction for the match head to ignite when rubbed against them. Smooth surfaces do not create enough friction to generate the heat required to light the match.
When an object rolls over a surface, the friction that occurs is called rolling friction. Rolling friction is lower than sliding friction, which occurs when an object slides along a surface. Rolling friction results from the deformation of the object and the surface it is rolling on.
A smooth surface typically has the least amount of friction compared to rough surfaces. Friction is lower on smooth surfaces because there are fewer irregularities that can impede motion. Examples of smooth surfaces with low friction include ice, waxed hardwood floors, or polished metal.
