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.
Friction between solids can be most accurately define as the force that enhances the sliding motion of two surface that are touching each other?
if you on apex and it is not a true or false statement the answer is ((surfaces))

Can three surfaces create friction?
Yes, anything from 2 surfaces creates friction.
When two surfaces rub do the irregularities of one surface get caught on those of the other surface?
Yes, this is a true statement and causes friction.

What type of surfaces have little friction?
smooth surfaces
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.
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.
