Choose the correct statement(s).
The average velocity of a moving body can be zero.
The average speed of a moving body is always zero.
Average velocity=DisplacementTime
The average velocity of a moving body can be zero. For example, when the body reaches the starting point after some time the displacement of the body is zero. The average velocity is zero as the displacement is zero.
Average speed=Distance coveredTime
However, the average speed of a moving body can never be zero because it will cover some distance while moving.
