Question

when body is performing uniform circular motion its velocty changes at every poin true or false

Answer 1

Answer:

The statement is true that in uniform circular motion its velocity changes every moment

Explanation:

Velocity can be defined as the rate of change of displacement. The displacement in case of uniform circular motion changes every moment because the direction of the velocity changes every moment.

This results in the change in  the direction but not the magnitude of the velocity. As a result of this uniform circular motion is sometimes called an accelerated motion
