Lower above, and greater below. That's what enables the wing to create lift.
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.
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.
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.
For a wing producing lift, the velocity of the air above the wing is greater than that below the wing. The Bernoulli Principle (named for 1700's Swiss physicist/mathematician Daniel Bernoulli) can be used to estimate the lift generated by a wing due to the difference in velocities above and below the wing. However, contrary to some popular science texts, there is no requirement that the air molecules above the wing meet up with the air molecules below the wing exactly where they parted. The air moves faster over the top of the wing producing lift not because of its shape, but because of something called circulation, a flow pattern around the wing superimposed on the airflow. See the following links for an excellent explanation on this.http://www.av8n.com/how/htm/airfoils.html#sec-circulationhttp://www.eskimo.com/~billb/wing/airfoil.html
The upward force due to a pressure difference is called lift. It is generated when the air pressure below the wing is higher than the pressure above the wing, creating a pressure difference that causes the wing to be pushed upward.
Lower above, and greater below. That's what enables the wing to create lift.
It's not so much that the air pressure below a wing is greater as it is the pressure above it is less. The way a wing works, is the airfoil (shape of the wing) accelerates the air above the wing. Since the air is moving faster, it lowers the air pressure, resulting in a lower pressure above, and a higher(standard) pressure below, creating lift.
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.
In flight, the air pressure above the wing is less than that below it.
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.
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.
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.
Low pressure is created over the top of the wing while higher pressure is below the wing which generates lift.
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.
The air above an airplane wing in flight is at lower pressure than the air below the wing. Hope this helps.
Air pressure above the wing is relatively smaller than that below the wing because that is what generates the lift the plane needs to fly into the sky, but if it is the other way round, the lift won't be generated and the plane will remain on ground.
Gravity, from the Earth, pulling it towards the ground, and Lift, applied by the air due to pressure difference on the wings (high pressure below the wing, low pressure above the wing). The faster the glider goes, the greater the Lift. Gravity does not change however.
