How does the pressure distribution affect the movement of a wing?

The correct understanding of why lower pressure above the wing causes the wing to rise lies in the principles of aerodynamics, particularly Bernoulli's principle. As a wing moves through the air, its shape and angle of attack create a difference in airflow speed above and below it.

When the air flows over the curved upper surface of the wing, it speeds up, which results in a decrease in pressure according to Bernoulli's principle. Simultaneously, the air flowing beneath the wing experiences higher pressure due to the slower airflow. This pressure difference creates lift, which is the force that causes the wing, and consequently the aircraft, to rise.

This principle is fundamental in understanding how wings generate lift and the importance of pressure distribution in flight dynamics. Hence, the concept of lower pressure above the wing directly correlating to the wing's ability to rise is central to the function of any aircraft.
