Uniform Motion - why velocity is constant

Assertion : The equation of motion can be applied only if acceleration is along the direction of velocity and is constant. Reason : If the acceleration of a body is constant then its motion is known as uniform motion.

Assertion : In a progressive wave motion, particle velocity is constant at all time. Reason : This is because density of medium is uniform throughout.

Assertion : Linear momentum of a body changes even when it is moving uniformly in a circle. Reason : In uniform circular motion velocity remain constant.

Assertion : The average and instantaneous velocities have same value in a uniform motion. Reason : In uniform motion, the velocity of an object increases uniformly

Assertion : Magnitude of average velocity is equal to average speed, if velocity is constant. Reson : If velocity is constant, then there is no change in the direction of motion.

STATEMENT-1: In uniform circular motion acceleration is constant. STATEMENT-2: In uniform circular motion speed is constant.
