Question

Is the uniform circular motion an accelerated motion?


Open in App
Solution

  1. As the speed along the circular path is uniform, but not the direction, we can say that the velocity is changing.
  2. The rotating blades of a fan are non-uniform or the blades are moving with a variable velocity (This is because velocity is the speed in a specified direction).
  3. Furthermore, the rate of change of velocity is called acceleration.
  4. Thus, the blades of the fan have an accelerated motion, as there is a continuous change in velocity with respect to time.
