What does Bernoulli's law suggest happens as airflow speeds up over a wing?

• A. The air pressure increases
• B. The air pressure decreases
• C. The air becomes turbulent
• D. The air slows down

Answer: (B)

Bernoulli's law describes the relationship between the speed of a fluid and its pressure. According to this principle, when the airflow over a wing speeds up, the pressure in that region decreases. This phenomenon is essential in understanding lift generation in aviation. As air moves faster over the upper surface of a wing compared to the lower surface, the decreased pressure above the wing creates a pressure difference. This pressure difference results in an upward lift force that enables an airplane to fly. This principle is foundational in aerodynamics, illustrating how varying speeds of airflow can influence pressure dynamics. The interaction between airflow speed and pressure is not only crucial for wing design but also for understanding various aspects of flight and vehicle control.
