If you think about how two gears can engage each other, with the teeth of one fitting between the teeth of the other, this is more or less how two rough surfaces engage each other. Tiny protrusions mesh with other tiny protrusions, and they can push against each other.

Is the amount of friction greater between rough surfaces or smooth and Why?

Rough surfaces, the rougher the surface, the greater the friction.


Why does rough surface offer greater friction than a smooth surface?

Almost always.


Why causes a rough surface have greater friction than a smooth surface?

The peaks and crannies interlock.


Does surface type affect the force of friction?

Surface types can affect the force of friction because as the surface gets rough and rougher it has more friction and smooth surface has less friction. if we compare the affect of friction force on a ice and road. Road is much more rough than the ice chunk and if we slide a ice hockey puck on each of the surfaces, we get that smoother surfaces has less friction.


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

two rough surfaces :)


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.


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.


Does a rough surface have a lot of friction?

Rough surfaces do create more friction than smooth surfaces. How much friction is created depends on how rough the surface is.


What is much friction the smooth surface or the rough?

the rough surface creates more friction as to that of soft surfaced ones


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.


What type of surface provides a lot of friction?

Rough surface provides lot of friction.


How is friction applied?

Friction is applied, by making the surface of whatever you want to slide across it (the thing you want to apply friction to) is really rough. You can inscrease, and decrease the amount of friction acting on an object by changing the texture, material and smoothness of the surface. Smoother surfaces don't apply much friction to objects, and rougher surfaces apply a lot. An example of this, is Wellington Boots. They have rough underneaths, so you don't fall over - they apply a lot of friction.
