Re: Dirtside Question: Zero or low G combat

It's pretty much correct if you work from mathematical first principles.
I think the exact formula should be

SQRT (height above ground * planetary radius + (height above ground)^2)

but the extra (height above ground)^2 is so small it makes little
difference to the answer unless you're a long way above the surface.
