Question

Can the average velocity of a body be zero when the average speed of the body is non-zero?

Answer 1

1. Yes, the average velocity of a body be zero when the average speed of the body is non-zero
2. The average velocity is defined as the time rate of change of position.
3. The average speed is defined as the total distance covered by a body per unit of time.
4. Now, consider a body starting from point A to B and returning to point A. The body covers some net distance which is the actual length of the path covered by the body, but the displacement of the body is zero as there is no net change in the position of the body.
5. Thus, the average speed is not zero but the average velocity is zero.
