Current Events > Weren't the astronauts worried about jumping on the moon?

(+) Yeah! (+)

If they tried really hard, they might have been able to jump up 10 feet in the air. Isn't falling 10 feet enough to possibly break someone's leg? That would really have sucked so far from home.

They should find a way to do low gravity sports games.

Imagine playing Roundball and dunking from the 3pt line and people jumping up to block it in slow motion.

What if they jumped but didn't land? Just continued to float off into space

I think all that hopping around is what caused the moon to start moving away from us.

That's a good question

How far could you fall on the moon without hurting yourself

when the moon breaks your thigh 'cause you jumped way too high

that's amore

Well, the Moon has about 1/6th the gravitational pull of the Earth. So you would accelerate at 1/6th the rate as you would on Earth. So whatever height you consider the "hurting yourself" point on Earth, multiply that by 6 to get your answer for the Moon.

How about the rate of acceleration? Might that be faster on the moon with no atmospheric resistance?

Over large distances, sure. Not for the ones you would consider "hurting yourself" distance. The wind resistance to weight ratio of an average human is so small that it has a negligible at best effect over distances of a couple dozen feet or so. It's like dropping a bowling ball in a vacuum and dropping a bowling ball in open air. You're not gonna see any noticeable difference in landing time until you're basically dropping from the top of a skyscraper.

But what about the ones who are lactose intolerant

Although, thinking on it, the lack of atmosphere on the Moon (and thus the lack of a proper terminal velocity) does mean that something very interesting happens.

Over short distances, you will hit the ground sooner on Earth than you would on the Moon. For example, at 9.8 m/s^2 on Earth, if you fell from 9.8 meters you would land in 1 second. But on the Moon, if you fell from 9.8 meters, it would take about 6 seconds to hit the ground.

Over very long distances, however, on Earth you would accelerate until 122mph and then "coast" the rest of the way at that same speed until hitting the ground. But on the Moon, you would continue to accelerate past that 122mph. So if the distance was great enough, you would actually hit the ground on the Moon sooner than you would falling the same distance on Earth.

This also means that there is some distance, specific to every unique object, where the falling time on Earth and the falling time on the Moon are exactly the same. In theory, at least.

Ya, that's kinda what I was getting at.

Might not ever happen.

The terminal velocity on the Moon is probably non-lethal.

Like imagine if you fell all the way to the bottom of a deep pool. There isn't a speed fast enough to harm you.

Or never mind, post #14

Did you hear about the restaurant on the moon?

The food is great, but there's no atmosphere :3
