What else can I help you with?
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 happens to the force of friction as a cyclist goes faster?
As a cyclist goes faster, the force of friction remains relatively constant. The force of friction between the tires and the road depends on the coefficient of friction and the normal force, which do not change significantly with speed.
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.

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
What is an example of a unbalanced force causing to change in motion?
friction
Give an example of an unbalanced force causing a change in motion?
friction :)

What is an unbalned force?
An unbalanced force is a force that causes change in motion. A force must also overcome friction before an object will move.
What force causes an object to change direction?
gravity (up to down) friction
