Grav sim

Simple gravitational simulation of spherical bodies. This doesn't follow any real like constants or anything just adding vectors together with values I made up.

How to use

Run main.py with python >= 3.10 and pygame (not sure what version).

Left click once to create a circle. Move the mouse to determine the radius and click again to set it. The arrow that pops up represents the initial movement of the body.
