How does the roughness of a surface effect friction?
The rougher then surface the greater the frictional force. When a surface is rough and you put friction to it, it creates sparks while smooth surfaces when friction is added causes a slight stactic shock.
Is the amount of friction greater between rough surfaces or smooth and Why?
Rough surfaces, the rougher the surface, the greater the friction.
Is friction greater with rough or smooth surfaces?
Smooth
Does rough surfaces exert greater friction?
Yes. Think about two steep hills. One is covered in ice (smooth). The other is covered in sandpaper (rough). The ice covered hill would be MUCH easier to slide down. Thus, the friction is much LESS, on a SMOOTH SURFACE. Then the opposite must be true, that friction is GREATER on a ROUGH SURFACE.
Why some friction occur with seemingly smooth surface?
A smooth surface is not actually smooth; it may have many microscopic bumps on its surface.

Why does rough surface offer greater friction than a smooth surface?
Almost always.
What factors that affecting friction?
Friction actually depends on the roughness or smoothness of the surfaces of the object. Even some smooth objects that we usually see everyday (ex. glass, mirrorr,etc.) aren't that smooth when magnified by strong microscopes. They still have rough surfaces therefore they can also have friction. Factors that affect friction: 1.) Adhesion 2.) Surface roughness 3.)The area of an object which is in contact with the surface. The larger the surface in contact, the greater friction. 4.)The texture of the surface and/or the object. The rougher/more uneven the surface/object, the greater the friction. 5.) The weight on the surface. The larger the weight, the greater the friction 6.)The angle of the surface. The greater the angle of the surface, the greater the friction.

Smooth
Is friction greater when two rough surface are rubbed together or two smooth surfaces?
two rough surfaces :)

Is the force is greater on a smooth surface or on a rough surface?
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.
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 is it difficult to strike a match on a smooth surface?
Heat necessary to lit a match comes from friction between match head and the surface. Smooth surface gives way less friction.
