Question

In uniform circular motion, velocity of particle is:
A) constant
B) variable in magnitude
C) variable in direction
D) both a) and b)

Answer 1

C) variable in direction ✓

Because the magnitude remains the same but the direction of the body keeps changing! If the direction changes the velocity changes. If the velocity changes, ultimately the acceleration changes.

A brainiest mark would be very much appreciated.
