In this video, I attempt to show how video game gravity and/or air resistance is so odd by comparing it to the real world, and I try to explain why in-game gravity is the way it is.
This is quite an ambitious video for me, so in some areas I may be wrong in my analysis, particularly the jerk/jounce stuff. However, I did my best with the knowledge I have. Feel free to correct me in the comments.

I'm not sure what's up with the rendering errors at 12:36 and 32:49. Odd. Plz forgive my computer.
