Question

what is centripetal force? discuss the role of centripetal force in case of motion a car on a level road.​

Answer 1

Answer:

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.

Answer 2

Answer:

• A centripetal force is a net force acting on an object in order to maintain it moving in a circular motion.
• The friction between the tyres and the road provides the car with the required centripetal force to turn on a level road.

Explanation:

• Newton's first law states that unless moved on by an external force, an item will continue to move in a straight line. The centripetal force is the external force at work here.
• The centripetal force is provided by the friction between the tyres and the road.
