Question

(a) What remains constant in uniform circular motion ?
(b) What changes continuously in uniform circular motion ?​

Answer 1

Answer:

(a) In a uniform circular motion the direction of motion keeps on changing with the revolution. ... But in that uniform circular motion what remains constant is speed.

(b) Velocity of the body changes continuously in uniform circular motion.

Answer 2

1. When a body is in uniform circular motion, its speed remains constant but its velocity, angular acceleration, angular velocity changes due to change in its direction.
2. Velocity of the body changes continuously in uniform circular motion. It is continually shifting its direction when an object travels around a circle. Accelerating objects – either the velocity (i.e. the magnitude of the velocity vector) or the direction are objects which change their velocity.
