Question
On a flat, unbanked curve, what force provides the centripetal force required for a car to turn?
Correct Answer
Option D is the correct answer.
Detailed Explanation
The lecture states that on a level road, friction between the car tires and the road provides the centripetal force required to prevent the car from skidding.
Hint
Without friction, a car on an icy flat curve would continue in a straight line due to inertia, not follow the curve.
