Take this Mini-Quiz to check your understanding of the lesson material.

1. Does the tire's coefficient of rolling friction change with the weight of the car?

Yes, because weight determines amount of deformation

No, because weight is just the normal force and is independent of mu

Yes and no, depending on the type of rubber used in the tires

2. Why is the temperature of the tire a factor in friction?

It is an indication whether it will rain, which affects rolling friction

Rubber melts when the temperature is too high, thus lowering friction

Air pressure in the tire increases with temperature, thus changing the deformation

3. Is the rolling friction of a tire the only thing that slows down a car?

Yes, provided you include the weight of the car

No, since friction on the axles and air resistance must be included

It depends on how fast the car is going at the time

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
