Question

In a uniform circular motion , velocity of particle is ___ but its speed is ____

Answer 1

1)change
2)constant

Answer 2

Heya user ,
Here is your answer !!

In a uniform circular motion , velocity of particle is _Changing_ but its speed is _Constant_ .

This is because , at every instant , the direction in a circular motion changes .
Now , velocity is depended on direction .
So , as direction changes , velocity also changes .
On the other hand , speed being independent on direction , remains constant as the magnitude of the speed remains constant in a uniform circular motion.

Hope it helps !!
