Question

an unifirm circular motion speed of an object is____​

Answer 1

That is when a body moves in a circular path, the direction of speed is not the same at any two points. And when there is a change in the direction of speed of the body, its velocity is not uniform. Therefore, circular motion is accelerated even though the speed of the body remains constant.

Answer 2

Uniform Circular Motion means that the angular speed is constant; but it would not be uniform if the angular acceleration was not zero (meaning that the angular velocity was changing).
