Airplanes fly by using fundamental aerodynamic principles, primarily involving the forces of lift, thrust, drag, and weight. The interaction of these forces, governed by Newton's laws of motion, allows aircraft to achieve and maintain flight. The wings of an airplane are crucial for generating lift, while engines provide the necessary thrust to overcome drag and weight. The curved upper surface of a wing forces air to move faster over the top than the bottom. While the traditional "equal transit time" explanation (Bernoulli’s principle) is often cited, it’s incomplete. Wings redirect air downward. As air strikes the wing’s angled surface, it’s deflected downward, creating an upward reaction force (Newton’s Third Law). Faster-moving air above the wing reduces pressure (Bernoulli’s principle), while slower air below increases pressure, contributing to lift. However, even flat wings (e.g., paper airplanes) can generate lift by angling downward to push air. In this video, we have explain
