Question

define uniform circular motion can it be accelerated motion explain briefly

Answer 1

As an object moves in a circle, it is constantly changing its direction. ... Accelerating objects are objects which are changing their velocity - either the speed (i.e., magnitude of the velocity vector) or the direction. An object undergoing uniform circular motion is moving with a constant speed.

Answer 2

Acceleration is a vector quantity i.e. It has both magnitude and direction. During uniform circular motion, the speed remains constant but velocity keeps changing due to change in direction at every instance. Velocity, which is also a vector quantity, points in the tangential direction during every instant of motion. Hence, due to change in direction there is change in velocity and the motion is accelerated.
