PHY 101 Circular Motion Objective Question
Take CBT

Question

What is the primary purpose of banking a road on a curve?
Options
A To increase the friction between tires and road.
B To reduce or eliminate the need for friction to provide the centripetal force.
Correct Answer
C To make the road surface smoother.
D To decrease the centripetal force required for the turn.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The lecture explains that banking reduces or eliminates the need for frictional force to produce the centripetal acceleration, thus minimizing tire wear and tear.

Hint

This design feature allows a component of the normal force to contribute to the centripetal force.
