How can I make something fly in the air? Figured I should do some reading and here's what I found out. "Aerodynamics" is what I need to study and thus learning how to make my object fly effectively.

Here's what I found out,

There are actually two main things in aerodynamics, air(aerios) and force(dynamis). So simply put, aerodynamics is the relationship between air and force. You'll see in a moment how it all works out.
Everything around us has weight, due to gravity. So, how can something that's heavier than air fly? This is when we need a "lift" which is the opposite of weight. In able to make something fly, that object needs more "lift" than "weight".
Let's take the airplane for example, it can fly due it's wings. How? The wings are curved on the top and flat on the bottom allowing less air pressure on the top and more on the bottom. This is what allows the airplanes to move UP instead of down.

But that's not it, there's also something called "drag". "Drag" slows down objects, and the more air that hits the surface of the object, the more drag it has. This is why most airplanes have a curved front which allows it to have less drag.
Now comes "drag"'s nemesis, "thrust", which is the push that moves an object forward. An airplane MUST have MORE thrust than drag, or else all it would be doing is either falling, or moving backwards. Most of the "thrust" of an airplane comes from it's propeller and jet engines.

Well, there's what I learned, hope it helped.
