How are airplanes related to science?

That is a very complex answer, hopefully someone can fill in any holes I leave.

First, you have the Pauli exclusion principle which simply states no two object can occupy the same space. In this case it is the wings vs. the molecules in the air. so you have: (::::::: = Air, \ = the wing)

::::::::::

::::::::::

:::::::::\ <- the plane will travel this way

The law that gives the plane lift is Newtons third law, for every action, there is an equal and opposite reaction.

So, as the plane moves forward, due to the slant (, slope, angle) of the wings, the molecules in the air are forced downward.

:::::::::: :::::::::: :::::::::: :::::::::: :::::.\:::

:::::::::: :::::::::: :::::::::: ::::::.\:: ::::::::::

:::::::::\ ::::::::.\ :::::::.\: :::::::::: ::::::::::

As the wings move forward, the air is forced down, pushing the plane up. Same concept as your hand outside the car window... I still do that lol

Then you have the forward motion. Which starts with a chemical reaction of fuel being burned. The fuel burns and creates a small explosion which turns a turbine and triggers Newtons third law once again. Excluding a few detailed specifics that is how the plane gets its forward propulsion (being moved forward). If you have a plane with a propeller, then it is the same concept as the wings. The fuel explodes which turns a turbine which spines the blades. The blades move so fast it pulls the plane forward due to.... once again Newtons third law. A example of this is standing in front of a fan. A fan strong enough can knock you off your feet because of the air being forced to move. The fan usually does not move due to the blades not spinning fast enough and/or the unit is too heavy.

There also are factors of pressure on cabins at higher altitudes, but I think that would be getting into way more detail than needed.
