Theorem of lift

The Bernoulli's Theorem of lift explains how an airplane wing generates upward force. It states that when air flows faster over the top of the wing, the pressure there decreases compared to the slower-moving air underneath. This pressure difference creates an upward force called lift, which counters gravity. The wing's shape and angle help direct airflow to produce this effect. In essence, faster airflow on top reduces pressure, and the higher pressure underneath pushes the wing upward, enabling the airplane to fly.
