A simulation of a particle being gravitationally attracted to the center. You can change the power of gravity from within the code (currently set to 3).
You can use the D-pad to apply thrust, press A to clear the trail, and press B to change the current trail color.
You can modify the variables for starting position, starting velocity, starting trail color, viewport size, and physics steps per render frame. There is edge warp.
I originally intended to make something that would predict the future orbit path using a function, but then I realized that the path of an object under acceleration is a second order differential which I have no idea how to solve :P .
