nBody Simulations

I did a project in CS at school to simulate the movement of free bodies with gravity.



At each timestep, each body's force is evaluated with respect to every other body, vector summed, then applied. No sense writing out all the gory details here since I wrote this in a paper for class!

Here's the source, and a video clip of the simulation.

Note from 2012: don't judge my physics or writing by that PDF! Leaving it for posterity, but I've learned a bit since then...
