(a)

In a uniform circular motion, since the magnitude of velocity is constant therefore magnitude of angular velocity is constant. Uniform circular motion can also be denoted as U.C.M. in case of uniform circular motion, speed, radial acceleration, angular momentum, the magnitude of linear momentum remains constant.

(b)

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.

Answer 2

First Question :-

Note: In a uniform circular motion, since the magnitude of velocity is constant therefore magnitude of angular velocity is constant. Uniform circular motion can also be denoted as U.C.M. in case of uniform circular motion, speed, radial acceleration, angular momentum, the magnitude of linear momentum remains constant.

Second Question :-

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.
