The wing of a plane typically has a curved top and a flat bottom. The airstream hitting the wing goes straight under the flat part, but has to also go up above the high part, then it meets again at the rear of the wing. The curved upper area causes low pressure by forcing air molecules to go faster across the top to reach the rear at the same time (a faster air velocity generally creates less downward pressure).
The higher pressure below the wing forces the wing upward and lifts the plane off the ground.

Which of the modes of transportation stays in the air because it is less dense than the fluid through which it is moving?
An airplane stays in the air because it generates lift by moving through the air at high speeds and having a wing shape that creates low pressure above the wing and high pressure below it. This pressure difference creates lift that keeps the airplane aloft.
How does a wind lift?
Wind can lift objects by exerting force on them through pressure differences. When wind flows around an object, it creates an area of low pressure on one side and high pressure on the other. This pressure difference can generate lift, similar to how an airplane wing functions.
Demonstrate that Air movement can result in lift?
Air movement can result in lift through the generation of pressure differences. When air moves faster over the curved upper surface of a wing compared to the slower-moving air beneath the wing, it creates lower pressure above and higher pressure below the wing. This pressure difference generates lift, causing the wing and the object it's attached to (like an airplane) to rise.
What is the pressure differential involved in flight?
In flight, the pressure differential between the inside and outside of an aircraft is usually maintained at around 8 psi (pounds per square inch). This differential is necessary to ensure that there is enough oxygen for passengers and crew at high altitudes, where the outside air pressure is lower.
The lifting force on an airplane's wing does which of the following?
increases with speed
How airplane flies?
differential in wind speed over the wings produces high pressure under the wing and low pressure on top of the wing.
What happens when air above an airplane wing is moving faster than air below an airplane wing?
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.
Why does the lift on an airplane wing increase as the speed of the airplane increases?
The lift on an airplane wing increases as the speed of the airplane increases due to the Bernoulli's principle. Faster airspeed over the wing creates lower pressure, and higher pressure underneath the wing generates lift. This relationship creates more lift force as airspeed increases.
What is Lift and drag?
Lift is an aerodynamic force that results from the air passing over the curvature of the wing. It causes a reaction. A high pressure on the bottom of the wing and a lower pressure on top of the wing. As a result, high pressure wants to go to low pressure and so the wind is lifted into the air. Drag is the force opposite to thrust. It is created by the airplane as it moves through the air. The faster the airplane, the more the drag.
What creates lift on an airplane?
Lift on an airplane is created by the airflow over the wings. The shape of the wings, called an airfoil, causes the air to move faster over the top of the wing than the bottom, resulting in lower pressure on the top and higher pressure on the bottom, which generates lift. This lift force is what allows the airplane to overcome gravity and stay airborne.
Air above an airplane wing is moving faster than air below an airplane wing This causes the plane to?
Low pressure is created over the top of the wing while higher pressure is below the wing which generates lift.
Is there more or less pressure under the wing of an airplane?
There is more pressure under the wing than is on top of the wing. This is what generates the lift for flight.
What force is created by high pressure under a wing and low pressure above a wing?
The pressure difference creates lift, which is the force that allows an airplane to take off and stay airborne. This lift force is generated due to the difference in air pressure above and below the wing, with higher pressure below the wing pushing the aircraft up.
What type of air is above an airplane wing when it is flying?
The air above an airplane wing in flight is at lower pressure than the air below the wing. Hope this helps.
When an airplane is flying how does the air pressure above a wing compare with that below the wing?
In flight, the air pressure above the wing is less than that below it.
What does the increased pressure below an airplane's wing cause?
Lift.
How do airplanes stay in flight?
Planes stay in flight because of bernoulli's principle. When air passes over a airplanes wing. The air that goes on the top of the wing moves faster than the air the goes on the bottom. Thsi auses a low pressure system above the wing and a high pressure system beneath the wing. The high pressure below the wing pushes the airplane up allowing it to fly.
