Question

Q2. Can the average speed of a moving object be zero? Can the average velocity of a moving object be zero.
Justify?
​

Answer 1

Answer:

Explanation:

1. No, the average speed for a moving body will never be zero. As distance is the path travelled by an object, so distance cannot be zero. Hence, the average speed will never be zero.

2. Yes, the average velocity depends on the net displacement of a body so if a body starts from a position and comes back to same position after some time , the net displacement is zero . Consequently, average velocity is zero. While the speed depends on the actual path length covered .
