Question

Under what condition, is the magnitude of the average velocity of an object equal to its average speed?

Answer 1

(1) The average velocity is the ratio of total displacement and total time.

(2) The average speed is the ratio of total distance and total time.

(3) The condition under which the magnitude of the average velocity of an object is equal to its average speed is when an object is moving in a straight line as the magnitude of displacement in this case is equal to the distance traveled.

Hence, when the object is in a straight line, the magnitude of the average velocity of an object is equal to its average speed.
