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.

What is the pressure differential involved in flight?
The way an airplane wing (or helicopter rotor) works is by creating a pressure differential, or a difference in air pressure, between the top and bottom of the wing or blade. Nature abhors a vacuum, so a gas such as air will flow as quickly as needed to prevent one from forming. Curving the top of the wing forces the air to travel a further distance in the same amount of time. As the plane moves forward and the air rushes over the wing, it has less chance to press downward, allowing the air flowing beneath the wing to press upward with enough force to lift the wing (and the entire aircraft with it).
The lifting force on an airplane's wing does which of the following?
increases with speed
How is an airplane wing designed to lift the airplane.?
If straightened out, the top surface of the wing is longer than the bottom one. When air flows over the wing, it must travel faster over the top of the wing so there is less air pressure. higher air pressure on the bottom and lower air pressure on the top= LIFT. The higher the Airspeed the lower the air pressure is called Bernoulli's principle.
Why do different birds have different shaped wings?
The shape of the bird's wing is flat, so more air molecules may push it up, the shape is also like a glider.
Explain in detail what Bernoullis Principle is?
§ Like a airplane wing, at the top it is curved, and that creates longer distance from front to back then the straight bottom. This causes the air on top to travel farther and thus faster to reach the back, then the air underneath, is creating a difference in pressure between two surfaces
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?
From Bernoulli's theorem this results in the air above the wing to form a low pressure compared to the air beneath the wing. High pressure moves to low pressure so you get lift
Why does the lift on an airplane wing increase as the speed of the airplane increases?
The pressure above the wing be Save comes less than the pressure below the wing.
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?
Bernoullis principle says that as a liquid's flow rate increases the pressure of the fluid decreases (think of your thumb on a garden hose) When air ( fluid) flows over a wingsurface the shape of the wing directs the air to travel a greater distance, and its speed is decreased. The pressure difference below the wing (higher) relative to the pressure above the wing (lower pressure) creates lift as high pressure areas move to low pressure areas in an attempt to restore equilibrium
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.
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 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.
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.
How does the wing of an airplane affect how it flies?
According to the Bernoulli's principle "where there is high velocity there will be low pressure and viceversa" . air-crafts wings are so designed that the upper surface of the wing experience high velocity and low pressure while the lower surface experience low velocity and high pressure which helps the aircraft to take a lift.
