A paper airplane is a simple flying craft made by folding a sheet of paper into an aerodynamic shape. Often associated with childhood play and experimentation, paper airplanes vary in design, from basic dart-like models to complex gliders with intricate folds that improve flight stability. The principles of aerodynamics, such as lift, drag, thrust, and gravity, influence how far and how well a paper airplane flies. Many people enjoy testing different folding techniques to achieve longer flight distances or unique flight patterns. Beyond recreation, paper airplanes are also used in educational settings to teach basic physics and engineering concepts.Â
