There has to be lesser air pressure on the top of the wing to provide lift.

Is air pressure greater above the wing or below the wing?
Lower above, and greater below. That's what enables the wing to create lift.
Lift occurs because the air pressure on the top surface if an airfoil wing is?
Lift occurs in an aircraft wing because the wind speeds up as it goes over the top of it. The wind is traveling at relatively the same speed over the bottom. The faster air that travels over the top causes the wing to have lift because the air pressure is lower over the top therefore the wing 'rises' in a way. Hope this helps :)
What creates lift?
An aircraft in flight experiences an upward lift force, as well as the thrust of the engine, the force of its own weight, and a drag force. The lift force arises because the speed at which the displaced air moves over the top of the airfoil (and over the top of the attached boundary layer) is greater than the speed at which it moves over the bottom and because the pressure acting on the airfoil from below is therefore greater than the pressure from above,This is how planes get lift.
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
Dose lift have to be greater than weight for a plane to land?
If lift is greater than weight, the airplane proceeds up, away from the ground. If lift is less than weight, the airplane proceeds down, toward the ground.
Atmospheric pressure on the top of a wing in flight is?
Low. High on the bottom low on the top creating lift. The faster the airflow the greater the pressure difference and the greater the lift.
Is the pressure greater above the wing or the wing?
Lower above, and greater below. That's what enables the wing to create lift.
Is air pressure greater above the wing or below the wing?
Lower above, and greater below. That's what enables the wing to create lift.
How is lift created?
Generally, lift is created when the pressure below an object is greater than the pressure above it. For example: an airplane wing is curved on top to allow for air to seamlessly pass over, creating low pressure on the upper surface and the wing is obstructed on the bottom, creating higher pressure to lift the wing. As for a helicopter, the air is pushed down by the propeller, causing high pressure below the rotation plane, causing lift.
How airplanes can fly in air in spite of being heavier than air?
The air pressure under the wings is greater that the pressure over the wings creating lift.
What force acts on gliders in the air?
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.
Lift occurs because the air pressure on the top surface if an airfoil wing is?
Lift occurs in an aircraft wing because the wind speeds up as it goes over the top of it. The wind is traveling at relatively the same speed over the bottom. The faster air that travels over the top causes the wing to have lift because the air pressure is lower over the top therefore the wing 'rises' in a way. Hope this helps :)
How does the speed on an airplane help it fly?
The flow of air over the top surface of the wings provides the lift that holds the plane aloft. The greater the velocity of the flow of air over the wings, the greater the lift. If the plane slows down sufficiently, and the flow of air is reduced enough, there will not be enough lift to hold the plane aloft, and it will begin to fall. When that occurs, it is called a "stall."
What creates lift?

Why is air pressure greater below the wing's surface?
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.
What if lift is not equal but is greater than gravity while flying straight?
If the lift is greater than gravity then the airplane gains altitude.
What is the relation between lift force and mach number in supersonic speed?
The only relationship is that the greater the velocity of Air over a Lifting Body (Wing in general), the greater the LIFT. HOWEVER, you cannot say that the reverse is true...that is, the greater the LIFT the higher the Velocity. You can change Lift by changing the Wing DESIGN. When Landing an Airliner deploys its WING FLAPS to create greater Lift at lower velocities.
