Picking up a Hammer on the Moon

MichaelL says...

In this case, it is. Lift a 1 kg(mass) on earth 2 metres and drop it. If will hit the earth with a force of 9.8 Newtons. (F=m x a) That's its weight though we tend to use the kg instead of Newtons to express weight. To lift that mass, you would have to exert 9.8 newtons of force.

On the moon where acceleration due to gravity is 1/6 that of earth, that 1 kg mass would only weigh about 1.8 (9.8/6) Newtons. So it would take correspondingly less force to lift it.

So our astronaut should be able to easily push himself upright in theory.

The real reason he can't do it probably has more to do with the design of the suit (top heavy, not very flexible) and the loosely packed surface composition of the moon. Like trying to right yourself while wearing an inflatable sumo outfit in a McDonald's ballpit.

The high jump answer... when a high jumper clears 7 feet he is really just lifting his centre of gravity about 3-4 feet. He just twists his body horizontal to get his legs and feet over.

On the moon then, he would only lift his CofG about 18-24 feet (plus say 3 feet for his legs). So his record jump would be less impressive than you might intuitively think.

In other terms weight alone isn't the whole story (as I assume you well know).

A dildo! A bong! No, wait... a squid! Oh, I see, it's a person. The Heat Miser! No, Elvis! I know... it's Lincoln! Yep, there's his beard, alrighty. Wait a sec... that ain't Lincoln. Hmmm... Chuck Norris? Wait, what the hell is that thing? A bunny? One of those headless dudes from Serious Sam? What is he wrapping... around... Sumo wrestler! Headless Sumo wrestler! He's leaning against a cactus! Nope, he's TIED to the cactus for some reason. Now he's... I have no idea what that is, but it looks like it would make a cool lamp.

Well, I wasn't trying to put down the larger/native guys. They are crazy strong as well, but hide it under a nice cushion. I would love a chance to see a match in real life :]

It's pretty cool seeing a westerner fight it out in such a niche and nationally-identified sport.

I know he looks small compared to his opponents, but damn do you see his muscles!? Dude's strong yo!

Yup. Who would of thought that an athletic, muscular guy would be better at sports than big fat Japanese guys with man boobs.
