How does an airplane fly?

• The top of the wing is curved and fast air goes
  over it with low pressure.
• The bottom of the wing is flat and slow air
  passes it with high pressure.This gives the plane
  its lift.

• An airplane flies because the air has weight and
  the molecules are constantly moving.
• This has a force that will lift the plane in the
  air.
