Question

Give an example of a motion in which average velocity is zero, but average speed is non-zero.

Answer 1

Answer: When the object travels in a circular path, or in a path which has the initial point and final point the same ( like car race track) the average speed is not zero but average velocity is zero

Answer 2

Suppose a car covers a distance of 50 m in 5 seconds and comes back to the initial position in 5 seconds. The average speed of the car is 10 m/s, but the average velocity is zero because displacement is zero.

When the object travels in a circular path, or in a path that has the initial point and final point the same ( like a car race track) the average speed is not zero but the average velocity is zero.
