Question

Why is the motion of a particle along a circular path with a uniform speed said to be an accelerated motion

Answer 1

Because during a uniform circular motion the direction of the body is constantly changing. And as acceleration is a vector quantity it depends on direction also. Hence, it is say that the body is constantly accelerating.

Answer 2

Answer:

Because of changing velocity caused by changing of direction

Explanation:

Uniform circular motion is accelerated because the velocity changes due to continuous change in the direction of motion. ... Thus, for a body moving in a circular path at a constant speed, its velocity changes continuously. The change in velocity gives rise to an acceleration in the moving body.
