If the pressure is lower above the wing and higher below the wing, what will the airplane do?

• lift

• sink

• Neither lift or sink

If the pressure is the same above the wing that it is below the wing, what will the airplane do?

• lift

• sink

• Neither lift or sink

Which of the following is correct?

• Lower pressure is caused by the speed of the air over the top of the wing. Which means there is now higher pressure on the bottom of the wing. This causes a plane to lift.

• Higher pressure is caused by the speed of the air over the top of the wing. Which means there is now lower pressure on the bottom of the wing. This causes the plane to lift.

• Neither of these are correct.

• Both of these are correct.
