Controlled Variables
-Launch spot
-Height of throw
-Plane weight (standard sheet of lined paper)
​
Independent variable
-Distance of flight in meters
-Force behind the throw

​

The force of the airplane that makes it fly forwards is the motion of our hand throwing ti forward and then letting it go. The plane continues to go forward because of inertia. It will continue to go forwards until something acts on it like wind or gravity. In this case since it is a PAPER airplane the wind will greatly affect it because of the papers mass. The wind could either help or hurt the airplane depending on the design. Sometimes it could keep it in the air longer helping it resist gravity but other times it could cause the plane to go into gravity's force and hit the ground faster.
