Question

what is meant by uniform circular motion? Is the motion of a particular in uniform circular motion unaccelerated?​

Answer 1

Answer:

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

when the object moves around its circular path is called circular motion

Example: the movement of the Earth around the sun on its fixed path is called circular motion
