Question

Assertion- Magnitude of average velocity is equal to average speed, if velocity is constant.

Reason- If velocity is constant, then there is no change in direction of motion.

Answer 1

when an object travels the same distance every second, then the object is said to be moving with constant velocity. This means that the magnitude of the velocity (or speed) and the direction of the velocity both remain constant.

So both Assertion and reason are true and the reason is the correct explanation for the assertion.
