I built a ballistic projectile simulator in Python as a homework project for the Intro to Mechanics course. I took into account all forces I knew of, including the ones relating to atmosphere and Earth rotation; no handwavy "we assume air density is small" (or constant, for that matter, but physics gets so messy there I had to settle with approximation). Basically, it should simulate ICBM flight fairly accurately, given proper parameters. And best of all—it outputs a file that can be loaded to Google Earth and watched as an animation.

All code and explanations are available on my GitHub.
