Question

The velocity of a body in non uniform motion is -20ms 'at a given instant. What is its
speed at the instant? Will the average speed of the body necessarily be same as the
magnitude of it average velocity? Explain.

Answer 1

Explanation:

The quantity that tells us how fast an object is moving anywhere along its path is the instantaneous velocity, usually called simply velocity. It is the average velocity between two points on the path in the limit that the time (and therefore the displacement) between the two points approaches zero
