Question:

Under what condition(s) is the:
(A) magnitude of average velocity of an object equal to its average speed?
(B) magnitude of average velocity of an object zero while its average speed is not zero? [Pg. No. 53]

Answer: Verified

(A) The magnitude of average velocity is equal to the average speed when an object moves in a straight line without changing its direction.

(B) The magnitude of average velocity is zero while its average speed is not zero when the object returns to its starting point after covering some distance. In this case, displacement is zero, but distance travelled is not zero.
