Friction in Circular MotionMediumQuestion 30613

Question

A car turns in a horizontal circle on a flat road. The centripetal force is provided by:
  1. A
    Engine thrust
  2. B
    Static friction between tyres and road
    Correct
  3. C
    Kinetic friction
  4. D
    Air resistance

Correct answer

Static friction between tyres and road

Explanation

On a flat (unbanked) road, the tyres don't slide — static friction provides the centripetal force directed toward the centre of the turn.
