Question
If a bee flies from a petunia to a marigold, and then returns to the petunia,Group of answer choiceshis average position was zero.his average speed was zero.his average velocity was zero.his average acceleration was zero.
Solution
His average velocity was zero.
Here's why:
Velocity is a vector quantity, which means it has both magnitude (speed) and direction. When the bee flies from the petunia to the marigold and then back to the petunia, the total displacement (change in position) is zero because the bee ends up at the same place it started.
Average velocity is calculated as total displacement divided by total time. Since the total displacement is zero (the bee ended up back at the starting point), the average velocity is also zero, regardless of the time it took for the trip.
Note that this is different from average speed, which is total distance traveled divided by total time. The bee did travel a certain distance, so the average speed would not be zero.
