When a car goes around a curve (without skidding), on a level road,

Select one:
a. no friction force is needed because the car simply follows the road.
b. the friction force of the road on the car increases when the car’s speed decreases.
c. the friction force of the road on the car increases when the car’s speed increases.
d. the friction force of the road on the car increases when the car moves to the outside of the curve.
e. there is no net friction force because the road and the car exert equal and opposite forces on each other.

  1. F = m Ac
    = m v^2/R

    F increases as speed increases
