I'm not sure why position is "r", but F for force, m for mass, w for world (in a short function), N for, well, N - doesn't seem too bad. Math looks much worse i

I'm not sure why position is "r", but F for force, m for mass, w for world (in a short function), N for, well, N - doesn't seem too bad. Math looks much worse if you spell everything out.
