Question

2) A car goes around a circular curve on a horizontal road at constant speed. What is the direction of the friction force on the car due to the road?

Answer 1

Answer:

perpindicular to curve inward

Explanation:

Answer 2

• As we know that when a car takes a circular turn on a horizontal road, the centripetal force is the force of friction.
• When a car goes around a circular curve the centripetal force required for circular motion is provided by the component of the contact force between the road and the car tyres along the surface.
• When the car moves away from the circle static friction opposes the impending motion of the car.

Hence, the direction of the friction force on the car due to the road is perpendicular to the curve inward.
