Why is friction least effected by smooth surfaces?
Smooth vs. Rough surfaces. Rough surfaces have more surface area than smooth surfaces. This means that there are increased incidences of molecular reactions between the surface and object
Why do smooth surfaces produces less friction than rough surfaces?
Because there is less traction for an object to grab onto on a smooth surface rather than when an object runs over a rough surface.
Is the amount of friction greater between rough surfaces or smooth and Why?
Rough surfaces, the rougher the surface, the greater the friction.
What surface has the least amount of friction?
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.
Why does light reflect better off of smooth surfaces than rough surfaces?
smooth surface

Does a smooth surface reduce friction?
There is more friction between the surfaces of 2 smooth surfaces than one smooth surface because there is more surface area.

smooth surface
Why is there less resistance on a smooth surface?
Because friction is less on smooth surfaces. Smoother the surfaces, lesser the friction.
Why friction does not occur in smooth surfaces?
It is wrong to say that friction doesn't occur in smooth surface.. As ideally, no such surface exists, which has 0 value of friction. We can say that the magnitude of friction force is less in smooth surfaces as compared to that in rough surfaces. Friction opposes the motion of a body. When we go to the molecular level, we can see that the surface of a plane is not smooth but rough.. We cannot see that roughness through naked eyes. But the amount of roughness differs from object to object. The so called smooth surfaces have less roughness as compared to un-smooth surfaces. Hence, the magnitude of friction is LESS in smooth surfaces...
Why does some friction occur on smooth surfaces?
Some friction will occur on smooth surfaces because even the smoothest of surfaces isn't completely smooth. There are bumps and cracks on the face of the surface when "zooming in" to a microscopic level.
Which smooth surfaces reflect light?
Any smooth surface will reflect light. The better question is "How much light does each kind of smooth surface reflect?"
Why can you only see yourself in smooth and polished surfaces?
You can see yourself in smooth and polished surfaces because the surface is clean and not blurry. Also, you can't see yourself in certain smooth and polished surfaces, such as tan desks.
What are surface finishes that improve sliding motion?
Smooth lubricated surfaces.
