Wind Resistance
This experiment is much like the last.
The ramp stays the same angle. The variable that is changed is the amount of wind resistance.
These four measured how far the cars went at first and then put up a card and measured again.
The energy to move the wind out of the way is not available to move the car
so it does not go as far with a card than it did without.
With a larger card and the car goes even shorter distance.
They reported to the entire class.
