If the average speed of an object is zero,then its average velocity must be zero;but if its average velocity is zero,its average speed is not necessarily zero.

This statement is true. Average velocity takes into account the direction of motion, while average speed does not. Therefore, if the average speed of an object is zero, it means that the object has covered equal distance in equal time intervals in opposite directions, resulting in a net displacement of zero. Thus, the average velocity would also be zero. However, if the average velocity is zero, it could mean that the object has covered equal distance in equal time intervals in opposite directions, or has moved in a non-uniform manner resulting in a net displacement of zero, but may have covered unequal distances at unequal times resulting in a non-zero average speed.
