Question

name the physical quantities which remain constant and which changes in uniform circular motion

Answer 1

velocity will changes and speed remains constant

Answer 2

нєℓℓσ мαтє!

In uniform circular motion

Speed = Remain constant
Velocity = Changes

What do I mean?

In uniform circukar motion the velocity changes even when speed is constant because a continuos acceleration is applied which is perpendicular to velocity pointing towards center.

As direction only changes at every point hence velocity also keep on changing but with uniform speed.
