Velocity changes because option b: the direction of a car varies continuously.

  • Velocity is a parameter that incorporates both the direction and magnitude of an object's speed.
  • The speed is uniform in a circular track, which implies it does not change at any time interval.
  • However, the velocity of the car on the circular track is altering. This is because if one of the parameters controlling velocity is not constant, the velocity will be as well not constant.
  • When an object moves on a circular track, its direction changes at each point of the circle in relation to the centre.
  • Therefore, even while the speed remains constant, the distance changes, and so the velocity changes.
