Which principle explains why a wing generates lift?

• A. The Law of Conservation of Momentum
• B. Bernoulli's Principle
• C. The Law of Gravity
• D. The Second Law of Thermodynamics

Answer: (B)

The generation of lift on a wing is primarily explained by Bernoulli's Principle. This principle states that as the speed of a fluid (in this case, air) increases, the pressure within that fluid decreases. When an airplane wing, or airfoil, moves through the air, it is designed with a specific shape that causes the air to travel faster over the top surface than the bottom surface. According to Bernoulli's Principle, this faster-moving air creates lower pressure above the wing compared to the higher pressure below it. This difference in pressure creates an upward lifting force on the wing, allowing the airplane to rise into the air. Understanding this principle is crucial for grasping the fundamentals of aerodynamics and how wings are able to generate lift during flight.
