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 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.
What types of surfaces create the most friction?
If both of the surfaces on which friction is to be created are very rough, the friction will be more. The more rough the surfaces more friction we have.
How does the roughness of surfaces that are touching affect the friction betwen the surfaces?
The rougher the surfaces the greater the friction.
What are surfaces with very little friction?
Soap surfaces have very little friction.

Does friction depend on the types of surfaces involved and how hard the surfaces push together?
Friction does depend on the types of surfaces involved and how hard the surfaces push together. Friction would be very minimal if the surfaces were smooth and not pushing together too hard.
Can three surfaces create friction?
Yes, anything from 2 surfaces creates friction.
What type of surfaces have little friction?
smooth surfaces
Why is there less resistance on a smooth surface?
Because friction is less on smooth surfaces. Smoother the surfaces, lesser the friction.
Is the amount of friction greater between rough surfaces or smooth and Why?
Rough surfaces, the rougher the surface, the greater the friction.
A lower coefficient of friction indicates that the two surfaces in contact have less resistance?
Yes but make sure you are clear in your understanding between the coefficient of friction and the force of friction. The force of friction is the force that resists the motion of two surfaces moving against one another. The amount of friction is determined by the product of the coefficient of friction and the normal (perpendicular) force that is pressing the two surfaces together. The coefficient of friction is a unit-less constant, that indicates how two surfaces compare to two other surfaces that are being pressed together the same amount. If the normal force is the same on two pairs of surfaces the pair of surfaces with the lowest coefficient of friction will experience the lower force of friction.
How will different surfaces affect the speed of a roller skate on an incline plane?
It depends on its roughness of the surface. The roughness on the surfaces will tell you how much friction will be acting. It is believed that the friction is caused by the interaction of the particles at sub-atomic level. The greater the interaction between the particles, the greater the friction. The more rough the surface, the less area will interact with both surfaces. Different surfaces, will have different friction coefficients, which decide if the roller skate will slip or not slip.
