Question:

Complete the following: A car is moving in uniform circular motion. The direction of friction between the tyres and the path is _____________.

Show Hint

In circular motion, always identify the force acting as the centripetal force. For a car on a flat road, it's friction; for a planet orbiting the sun, it's gravity.
  • towards the centre
  • tangential to the path

The Correct Option is A

Solution and Explanation


For an object to move in a circle, it must have a net force acting on it that is directed towards the center of the circle. This force is called the centripetal force. In the case of a car turning on a flat road, the static friction between the tires and the road provides the necessary centripetal force. Therefore, the direction of friction is towards the centre of the circular path.
