Question

Jennifer and Mark make paper airplanes. They are conducting an experiment to see which airplane design will travel a longer distance. What do they need to do to properly conduct their experiment?

Apply the same force of motion when they release the airplanes.
Apply different forces of motion when they release the airplanes.
Throw one airplane into the wind and the other airplane against the wind.
Use the force of the wind to decide which will travel farther.
