Question

which of the following statements are true? Refer to the diagram below as needed A car going 72 mgh will requlre a greater centripetal force to go around curve A than to go around curve B. A car going 44 mgh will requlre a greater centripetal force to go around curve B than to go around curve A. For a car taking either curve the centeripetal force is provided by the static friction between the tires & the road. For acar taking either curve the centeripetal force is provided by the normal force between the tires & the road. The slower a car goes around a curve the more centripetal force it requlres. The slower a car goes around a curve the less centripetal force it requlres.

Explanation / Answer

Centripetal Force is F = ma = mv2/R

1. True, dividing by a larger radius will make a smaller force

2. False, more force is needed for the smaller radius

3. False, friction is another force, it doesn't cause centripetal force

4. False, normal force is anther force

5. False, a slower velocity results in a smaller centripetal force

6. True, a slower velocity results in a smaller centripetal force
