Question

The ratio of magnitude of average velocity to average speed is greater than or equal to 1.

• A. True
• B. False

Answer 1

The correct option is B False

Average velocity of the body is defined as the ratio of net displacement of the body to the total time taken.

Average velocity $v_{avg}=\frac{Displacement}{Time}$

Average speed of the body is defined as the ratio of total distance of the body to the total time taken.

Average speed $s_{avg}=\frac{Distance}{Time}$

Since we know that the magnitude of the displacement can either be equal to or smaller than distance covered, thus average speed can either be equal to or greater than magnitude of velocity.

Thus the given statement is false.
