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.
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.
What are all factors affecting frictional force?
Mass, the bearing surface (how much weight on what surface area), and a "coefficient of friction", a measure of how rough or smooth the surface is.
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 greater force needed to move an object over a smooth surface than over a rough surface?
No because an object is much more easily pushed on a smooth surface than a rough because the rough surface will take more effort and energy because of it harsh surface

What things control how much friction is present?
how hard you press and how smooth a surface is

Why does rubbing of a matchstick on a rough surface lights up?
The rough surface causes a lot of friction when the matchstick rubs against it. Friction causes heat (try this for yourself by rubbing the palms of your hands together- they feel hot. Then consider how smooth our skin is in comparison to the rough surface, so you appreciate how much heat it generated.) The heat causes the wood of the matchstick to set alight. Actually, the head of the matchstick is coated in a more flammable substance (phosphorus), which makes lighting even easier.
What type of surfaces might cause a toy car to roll faster or slower?
Faster: Surfaces with less friction (smooth) ;slanted surfaces Slower: Surfaces with more friction (sticky surfaces, rough surfaces), uphill surfaces Of course a slanted surface with too much friction will also make the car slower.
How do you make a ball roll slowly down a ramp?
apply friction a rough surface cardboard for example, the rougher it is the slower the ball will roll but to much friction and it will stop altogether.
Why is it important for the roadways to have rough surface?
Roads have rough surfaces because it cause more friction which a) slows down the car and b) because it stops the car swerving as much.
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.
What do you use Smoothing Plane for?
A smoothing plane is used to level or smooth rough wooden surfaces. Function is variable; however, it was designed to be used with wood. It can be used, for example, to smooth and level a rough-cut surface; or to consistently remove thicknesses from the exterior of a piece of wood. It is much more efficient than beginning to smooth a surface with extra-coarse sandpaper.
