Question

The magnitude of average velocity is equal the average speed when a particle moves

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.

Answer 2

The average velocity is equal to the average speed when the particle moves in a straight line in a single direction.

• Average velocity is defined as the ratio of the total displacement and the total time

$avg. \: v = \dfrac{displacement}{time}$

• Average speed is defined as the ratio of the total speed and the total time.

$avg. \: s = \dfrac{distance}{time}$

For the average velocity and the average speed to be equal, value of displacement and distance has to be same.

This is possible when the particle travels in a straight line in a single direction.
