Lucky for him gravity on the moon is only 1/6 that on Earth.

Unfortunately, his space suit weighs three times as much as *he* does. Still, that's a net gain -- he only hit the ground with half the force he would have on Earth.

You're forgetting Galileo - objects fall at the same speed despite their mass. This is especially true on the moon, where there's no air resistance, so a feather hits the ground the same time as a rock. So, he only hit the ground 1/6 as hard.

Heavier objects hit the ground at the same speed lighter ones do, but I meant how HARD the impact is. Heavier objects are more massive and carry more energy than lighter ones, even at the same speed. It's easy to demonstrate. Roll a skateboard down a hill for about 20 feet and stop it with your foot. Try the experiment again with a Toyota. Even ignoring the effects of friction, you should have a much harder time time stopping the Toyota.

This is true. However, a more massive suit would also absorb more of the impact. When a semi hits a Prius, which driver is more likely to survive? Also remember, those suits are basically balloons, so they would probably be excellent protection against falls. Take for example, the "anti-bear" suit. It's massive, yet allows the wearer to fall as much as twenty feet without injury.
I think we're going to have to call in Mythbusters to resolve this debate once and for all.

That's something else -- the extra mass takes more force to accelerate from zero speed, and that force comes from the formula F=ma2, where the mass of the impacting body provides the force. Totally different from freefall in a gravity field.

Yes, which why things fall at the same speed - there's more force on the object, but that force has a greater load to work on.

Actually, things fall at the same speed because of the sign next to the drop with the posted maximum speed limit.

Not if there's a yellow light.

A yellow light does seem to exhibit many of the properties of a black hole, accelerating all objects toward itself.

Those outside the spaceship sensors suddenly doesnt seem as silly, does it?
