TopicWeren't the astronauts worried about jumping on the moon?

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.
