Here's why:
* Average velocity is defined as the total displacement divided by the total time taken.
* If the average velocity is zero, this means the total displacement must also be zero.
Example:
Imagine a car moving forward, then stopping, then moving backward the same distance it moved forward. It ends up in the same position it started.
* The total displacement is zero.
* Even though the car moved, its average velocity is zero because its displacement is zero.
Important Note: While the displacement is zero, the distance traveled might not be zero. The distance traveled is the total length of the path taken, regardless of direction.
