Barely at all, I'd say.

The force of hitting someone -- or resisting being hit -- depends
mostly on how your feet are braced, and how your weight is balanced
above them. (For a sitting person, even more so, because his butt and
back are braced too.) If someone is balanced badly, you can literally
knock him over with one finger. If he's set right, he can push back as
hard as you can push.

On Mars, you'd probably have a different form -- maybe slower, with
more lead-in and follow-through. But the final power would be similar,
because it's ultimately your inertia that's behind a punch.

It'd be different if you were pu****ng a very heavy object (or a wall).
In that case, you really are limited by floor friction; you set your
feet to push as hard as you can without slipping. Friction is directly
pro****tional to gravity. But a boxer doesn't fail by punching so hard
that his feet slip backwards; that's just not the bound on his
performance.

argue in favor of torture, set up legal justifications for torturing
someday, then the moral rot has *already* set in.
