Question

Which of the following statements are correct for a round trip along the circular route?

• A. Average speed is zero in a round trip
• B. Average velocity is zero in a round trip
• C. Average velocity and average speed, both are non-zero
• D. Average velocity is non-zero because displacement is non-zero.

Answer 1

The correct option is B

Average velocity is zero in a round trip

The average speed depends on the total distance travelled which is non-zero in this case. On the other hand, the average velocity depends on the total displacement of the body, which in this case is zero.
