Flight is the motion of an object through the atmosphere, governed by the principles of aerodynamics and fluid dynamics. The ability to sustain flight requires generating sufficient lift to counteract the force of gravity, while simultaneously managing drag and providing forward thrust. Aerodynamic lift is generated by the differential pressure created over a moving airfoil, often resulting from a curved or cross-sectional shape that forces air molecules to travel at varying speeds. The study of flight encompasses both biological mechanisms, observing the complex musculature and structural adaptations used by various taxa, and technological applications, involving the design of increasingly efficient airfoils and propulsion systems. Whether achieved through flapping wings or fixed-wing rotation, successful flight necessitates balancing the four fundamental forces: lift, weight, thrust, and drag.
