Here's why:
* Average Velocity: Average velocity is calculated as the total displacement divided by the total time taken.
* Displacement: Displacement is the change in position of an object from its starting point to its ending point. It's a vector quantity, meaning it has both magnitude (size) and direction.
Example:
Imagine a car that travels 5 km east, then 5 km west.
* Total Distance: The car traveled a total distance of 10 km.
* Total Displacement: The car ended up back at its starting point, so its total displacement is 0 km.
* Average Velocity: Even though the car traveled for some time, its average velocity is 0 km/h because the displacement is 0.
Key Points:
* Zero Displacement: If an object ends up at the same position where it started, its displacement is zero, and its average velocity will also be zero.
* Non-Zero Distance: Even if an object travels a non-zero distance, its average velocity can still be zero if the displacement is zero.
