Average velocity is different than average speed because calculating average velocity involves

Displacement

Explanation:

We are given that average velocity is different than average speed.

We have to find what involves average velocity.

Average velocity:It is defined as the displacement per unit time.

Mathematical representation,

Average velocity=

Average speed:It is defined as the distance per unit time.

Average speed=

Average velocity is different from average speed because calculating average velocity involves displacement but average speed involves distance.
