Question

If the centripetal and thus frictional force between the tires and the roadbed of a car moving in a circular

path were reduced, what would happen?

A. The car would continue to move in the circular path.
B. The car would stop moving instantly.
C. The car would slow down.
D. The car would begin to move in the direction it was headed in a straight line.

Answer 1

The correct answer is D (just took the test) Good luck! 

Answer 2

Answer;

D. The car would begin to move in the direction it was headed in a straight line.

Step-by-step explanation;

-Centripetal force is any net force causing uniform circular motion. The direction of a centripetal force is toward the center of curvature, the same as the direction of centripetal acceleration.

-The centripetal force causing the car to turn in a circular path is due to friction between the tires and the road. A minimum coefficient of friction is needed, or the car will move in a larger-radius curve and leave the roadway.

-Therefore,If the centripetal and thus frictional force between the tires and the roadbed of a car moving in a circular path were reduced then the car would begin to move in the direction it was headed in a straight line.
