Question

Which of the following quantities remains constant in uniform circular motion?
(a) Velocity
(b) Speed
(c) Acceleration
(d) Both velocity and speed

Answer

(b) Speed

Reason — In uniform circular motion, where an object travels along a circular path at a constant speed, the direction of motion changes continuously, implying the presence of acceleration. Hence, velocity changes due to change in direction and speed remains constant.
