This storyboard does not have a description.
I wonder what your average speed is.
I went at a speed of 4 m / s
Two kids want to find out what their average speed is on this bicycle.
I wonder what the velocity was.
The formula to find the average speed is distance / time. The distance the boy on the bike traveled is 20 m. The time it took was 5 s.
The formula for velocity is distance in a direction / time.
So, the average speed is 4 m / s.
We were moving North and didn't change direction, so our velocity was 4 m / s North.
The kids also want to know what their velocity was.
The formula for velocity is distance in a direction / time. So velocity changes due to change in speed, direction, or both.
They knew they were moving North, so their velocity was 4 m / s North.
