Question

under which condition is the magnitude af average velocity equal to average speed
​

Answer 1

Answer:

Average velocity would be equal to average speed when the total distance travelled equals the net displacement of a particle. This happens when a particle moves along a straight line in a fixed direction.

Explanation:

If the motion of an object is along a straight line and in the same direction, the magnitude of displacement is equal to the total path length. In that case, the magnitude of the average velocity is equal to the average speed.

Answer 2

Answer:

When an object moves along a straight path without change in its direction, the average velocity of an object is equal to its average speed.
