Questions & Step-by-Step Solutions

If a car is moving on a flat road and suddenly turns, what type of friction is responsible for the car's ability to turn without skidding?
  • Step 1: Understand that when a car is moving straight, it is using kinetic friction to stay on the road.
  • Step 2: When the car turns, it needs to change direction.
  • Step 3: To change direction, the car must have a force acting towards the center of the turn.
  • Step 4: This force is called centripetal force, which helps the car follow a curved path.
  • Step 5: Static friction is the type of friction that acts between the tires and the road when the tires are not sliding.
  • Step 6: Static friction provides the necessary centripetal force to keep the car on its curved path without skidding.
  • Step 7: If the static friction is strong enough, the car will turn smoothly; if not, it may skid.
  • Static Friction – Static friction is the force that prevents two surfaces from sliding past each other. In the context of a car turning, it provides the necessary grip to change direction without skidding.
  • Centripetal Force – Centripetal force is the net force required to keep an object moving in a circular path. In this case, static friction acts as the centripetal force for the car.
