A simple simulation of bodies with gravitational attraction and elastic collisions.
In this simulation, the gravitational constant, G, is not the same as it is in the real world. This is to make both its value and the required mass values for the bodies easier to work with.
If you want to play with this yourself, clone the repository and open the
index.html file in a browser. To change the properties of the bodies, edit
the code in the getBodies function.
A demo can be found here.
