If friction isn't dependent on surface area but only on the coefficient of friction between two surfaces and the reaction force then why do racing cars use bigger tires with greater area?
Friction doesnt not depend on the surface area...but the force of friction does! We cannot change the friction of a material but we can change the force due to that friction on another material in contact with it. Using this concept, racing cars have bigger tires to minimise the force of friction acting on them. They cannot change the friction of the road, so they change the resultant force on the tires.
If normal force is dobledwhat happens to friction?
Frictional force gets doubled. But coefficient of friction does not change
Does friction have force?
Yes,friction have force because if there is no force then friction cannot take place. Force is a thing 1.from which we can move from rest 2.from which we can change the state of motion 3.from which we can change the shape of an object 4.from which we can change the direction of motion of an object 5from which we can the speed of an object
What is a Force that keeps 2 object that are touching from easily sliding past each other?
None. Change your question for two OBJECTS and the answer is friction.
What are two ways that a force can change speed?
friction \
How is friction a force?
Due to friction velocity of a body gets reduced, reduction in velocity causes change in velocity. This change in velocity leads to production of acceleration.(Because only acceleration can produce change in velocity either its direction or its magnitiude). And only a force can cause the acceleration hence friction is a force.

What is an example of a unbalanced force causing to change in motion?
friction
Does the mass of an object affect friction-?
Yes Friction=Reaction force x COF Reaction force = mass x gravity So Friction=mass x gravity x COF ^ Change the mass, change the friction
Give an example of an unbalanced force causing a change in motion?
friction :)

How does the coefficient of friction depend upon the normal force between the surfaces in contact?
-- The friction force changes, and is directly proportional to the normal force. -- The coefficient of friction doesn't change. It is the proportionality constant in the first statement.
