      Hi Reon,
      If I remember my physics correctly I think it’s to do with air pressure differences caused by the shape of the plane’s wing. Air flows quicker over the top of the wing, which means the air pressure is lower on top. This means there’s an upward force that pushes the wing up which keeps the plane up. The force is bigger when the air over the wing is moving faster, that’s why planes need to reach a certain speed before they can take off.
      Thanks for you question 🙂
