5. What are the two factors that affect friction?

Explain why the aperture of the spherical mirror should be small compared to the radius of curvature of the mirror.

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.

The speed of light can be used to measure the
