A car is moving around a tree in a circular path. What can be said about the average velocity?

(a) It is non zero

(b) It is zero

(c) It is greater than zero

(d) It is less than zero

This question was addressed to me in an international level competition.

I'd like to ask this question from Straight Line Motion topic in portion Motion in a Straight Line of Physics – Class 11

Best answer
The correct answer is (b) It is zero

The best explanation: Take any point on the circular path. The car moves in a circle and hence will come back to the same point after a definite time interval. Therefore, the displacement is 0. Hence, the average velocity is zero.
