How do airplanes fly?
Airplanes are a type of flying transport that will get you from one side of the earth to the other. The first flight of an airplane was the wright brothers who flew the first successful airplane on December 17, 1903. There are four forces of flight Thrust, Drag, Lift and Weight.
Thrust is produced by the big engines located on the plane’s wings. Thrust helps create the force that makes the plane fly, lift. Thrust has to overcome drag for it to go forward. For example if I threw a paper plane my arm would give it thrust.
Drag goes the opposite direction as the object. Drag is caused by everything of the plane. Drag is the force that slows down the object going the other way. If the plane was to take off drag must be lower than the thrust.
Weight on a airplane is caused by gravity. Weight acts in a downward direction toward the center of the earth. During a flight the aircraft burns up its fuel, so the weight of the airplane constantly changes.
Lift is the force that prevents the weight of an airplane and holds the airplane in the air. Lift is created by differences in air pressure. Most of the lift is generated by the wings.
This is great!
