While the plane is flying forward, air moving over and under the wings is providing an upward lift force on the plane. At the same time, air pushing back against the plane is slowing it down, creating a drag force. The weight of the paper plane also affects its flight, as gravity pulls it down toward Earth.Feb 28, 2013
Aerodynamics. As with real airplanes there are four main forces, called aerodynamic forces, that enable a paper plane to stay in the air. The first one, when you throw the plane forward, is called thrust. Lift is a force that acts on the wings and helps the plane to move up.May 8, 2015
The bigger the wingspan of the plane, the more air pushes up. ... My hypothesis was that longer paper airplane will fly farther than a wide paper airplane. I think this is true because the tip of the longer plane will cut through the air which will reduce air resistance and allow it to fly farther.Jan 10, 2014
