Low pressure is created over the top of the wing while higher pressure is below the wing which generates lift.
That's true for the airplane's wings, when the airplane is flying upright.
Bernoulli's principle explains how the faster-moving air above an airplane wing creates lower pressure, while slower-moving air below the wing creates higher pressure. This pressure difference generates lift, allowing the airplane to fly.
above the wing moving faster above the wing causes a lower air pressure relative to below the wing. high pressure moves to low pressure causing lift.
above
moving the air above it
The air pressure above the wing is lower because the air traveling faster over the curved top surface creates lower pressure compared to the slower-moving air below the wing. This pressure difference generates lift, allowing the airplane to fly.
When the air above an airplane wing moves faster than the air below it, a pressure difference is created. This pressure difference generates lift, as the higher pressure below the wing pushes the aircraft upward. This is known as Bernoulli's principle, where increased air speed above the wing results in decreased pressure and lift.
Air moves faster over the top of a wing, and slower under the wing. The faster moving air above the wing has a lower pressure than the slower moving air below the wing. This causes lift, or the tendency for the wing and plane to move upward.
Airplane wings are shaped such that the length of a path from the leading edge of a wing to the trailing edge is longer when going over the top than across the bottom. For this reason, air going over the wing must travel faster than air traveling beneath the wing.
Faster-moving air across the top of the wing lowers the pressure there. For a plane to ascend, the pressure must be sufficiently lower on top of the wing, and it will be forced upward by the greater pressure below the wing.
As air molecules move over and under the wings of an airplane, the pressure decreases above the wings and increases below them, creating lift. This difference in pressure generates an upward force that allows the airplane to rise into the air. The phenomenon is explained by Bernoulli's principle, which states that faster-moving air has lower pressure.
That's "principle", not "principal". The idea is that the airplane's wings are shaped in such a way that the air moves faster on the top than on the bottom. As a result - and applying Bernoulli's principle - there is less pressure on the top of the wings.
