On the moon, there's only one sixth of earth's gravity. So, if one jumps off a cliff, let's say with a 1500 feet straight drop, hitting solid ground on the bottom, will he survive or die? And why?
(Please disregard the lack of oxygen, extreme temperatures, and all those other facts that have nothing to do with the core of the question; let's assume that the moon has the same conditions as earth, except gravity).

A 1500 foot fall on the moon would be equivalent to a 250 foot fall on earth; it would probably be fatal. On level ground, you could leap six times higher, but would land with the same velocity as with a leap on earth: your muscular output supplies the energy, and that doesn't change.

Oh, the lack of an atmosphere is most important. On the earth, you will reach a terminal velocity because of air friction. With no atmosphere on the moon you will just keep accelerating. Fall far enough on the moon and you die. Even a weak accelration gets you to a high speed over a decent time interval. If you fell the 1500 feet you mention, you'll hit at about 120 feet per second (around 80 mph). That's probably lethal.

Insufferable thinker of questions that you'll never have a sure answer for? Anyways, my best guess is that since we would weigh one sixth of our weight on Earth, the same would happen with acceleration, which would decrease to 1.6 meters per second, and since the human body can resist a fall from just about 12 feet without serious injury, a 200 pound man would probably stand a free fall from 100 feet on the moon, but probably not more than that. Just blurted out the result, but there's the facts you'd have to consider if you really want to give it some thought.

consider that the gravity of earth is 6 times as the gravity of the moon, so the 1500 you drop on the moon will be the same as 250 drop here on earth, now the question is: can you survive a 250 feet drop here on earth??

Now consider this: you jump from a small wall about 5 ft here, you should be fine, right? now consider it's equivalent jump on the moon, 5 * 6 = 30 ft, so when you jump 30 ft on the moon, you should be fine, right?

At that height you would hit harder because there is no air resistance and the actual impact would be a lot gorier. The splat would be larger and more dramatic due once again to the lack of atmosphere. You could however, survive a fall from a fairly tall building. 1500 feet is just to much...
