Without air resistance, bodies travel in a parabola.
What is the curve that is travelled when air resistance is included? I found that there are different air resistances, which curves would these types produce?

With air resistance, you don't get a nice curve (such as a simple parabola). I don't think there is a special name for all those types of curves you can get.

Some objects (mainly small objects) can have laminar flow where drag grows linear with the velocity.
Unfortunately, their typical timescale is so short that you cannot really call their motion "falling".

Short answer: there is no simple closed form except in very extraordinary circumstances.

And? It doesn't follow from this that what I wrote in my post was wrong. I pointed out that there were cases with air resistance in which analytical expressions could be found, I did not say that that was generally true.
