Cars and Curves Goal: Contrast the forces that cause cars to bank. A car goes around two different types of curves: a flat curve with friction and a banked frictionless curve. (a) Which force is responsible for holding a car in an unbanked curve? (a) the car's weight (b) the force of friction (c) the reaction force to the car's weight (d) the vertical component of the normal force (e) the horizontal component of the normal force (b) Complete the following statement: The maximum speed at which a car can safely negotiate an unbanked curve depends on all of the following factors except: (a) the diameter of the curve. (b) the acceleration due to gravity. (c) the coefficient of static friction between the road and the tires. (d) the coefficient of kinetic friction between the road and the tires. (e) the ratio of the static frictional force between the road and the tires and the normal force exerted on the car. (c) Applying the correct physics, demonstrate why the answer to (b) is correct.

When car goes around circular curve on level road without slipping: no frictional force is needed because the car simply follows the road the frictional force of the road on the car increases when the car speed decreases the frictional force of the road On the car increases when the car speed increases. the frictional force of the road on the car increases when the car moves to the outside of the curve: there is no net frictional force because the road and the car exert equal and opposite forces on each other:
