Physics Of Paper Airplanes
Most people believe that a paper airplane is a very basic childrens toy that is cheap as well. But beyond the fun and excitement that is gained from playing with paper airplanes, there is a lot to learn about the physics of the plane. Certain factors determine whether or not a paper airplane, which acts as a glider does, will fly well. Some of these factors include lift (which is connected to air pressure), drag and weight.
Paper airplanes must generate enough lift to oppose the weight. The plane gains lift by moving through the air with the initial velocity that is created by throwing the plane. But, because the plane is flying through the air, it has drag, which is an opposing force like friction on the ground. The paper airplanes velocity will quickly decrease, due to the drag, and the plane will fall to the floor.
In terms of physic, the airplane is staying afloat because it is trading potential energy for kinetic energy, which equals velocity. As the gliders lose altitude, they convert potential energy into kinetic energy, which keeps the plane in motion. This is
