Question

Is the uniform circular motion an accelerated motion?

Answer 1

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.
