The weight of a person on the Moon will be about six times less than on Earth. Suppose if your character weighs 80 kg, then on the moon it will weigh only 13. This is the approximate mass of a teenage bike. Therefore, in order to move on the Moon in proportion to the movement on Earth, you need to make six times less effort. Well, or with the same efforts, a person will be able to jump three meters. If this is an easy run, then about half a meter.

In this case, the step will be taken with complete separation from the road surface (or where he runs) and will be about four meters in length. It will not be like running, but like long long jumps. See how the American astronauts dashingly jump there:

And by the way, only the spacesuit weighs about a hundred kilograms ... The astronauts moved in light dashes. After all, a spacesuit is not a very comfortable thing.

With low energy costs, a small refreshing run can stretch for tens of kilometers. Feelings are quite difficult to convey, if only because no one has done this before us.

The steps, by the way, will be higher there. I don’t know why I’m writing this, but if the gravity on the Moon is less, then there is no need to make such small steps. The ceilings in the houses will also be high, about five meters, so as not to bang your head when you run to the toilet.

By the way, when you run, you don't have to jump high. For a person to walk on Earth, you need to accelerate at an angle. Something in between lifting up and pushing forward. On the Moon, gravity will be six times less, as I already said, therefore, a person can not jump up, but direct more acceleration forward. When you walk waist-deep in water, you can also feel this - the water pulls you down less and you spend more energy on overcoming the path forward, which is why you have to lean forward and push off the bottom horizontally:

The easiest way to describe the movement on the surface of the moon is jumping on a trampoline. Of course, everything is far from the case there, but there is definitely a share of similarity in this. Have you tried running on a trampoline in children's amusement parks? Here on the moon is about the same, only the soil underfoot does not crumble. Try to launch a child there, capture his fun on video, and then slightly slow down the video sequence.

That is, if you jump five meters on the moon and five meters on Earth, the difference will be significant. First, on Earth, you will have to communicate more energy to lift on takuheight, hence the initial velocity on Earth will be greater. The same with landing, five meters on the Earth - a fracture, on the Moon - in proportion to the earthly jump from the table. A man on the moon will move more slowly, but if he needs to accelerate along, the speed will be higher and pick up faster. The truth will look strange, as if it were a giant. But that's okay.

There are other inconsistencies. The fact is that for a person to breathe without a spacesuit, a rather dense atmosphere is needed. To have a dense atmosphere, you need an attraction, like that of the Earth, otherwise everything will evaporate into space. In this case, you need to figure out how, by ennobling the moon, you managed to create a dense atmosphere with low gravity.

You will also have to explain how you managed to accelerate the rotation of the moon around the Earth thirty times faster. After all, the synodic period of circulation (a day on the Moon) is approximately equal to 29 days, 12 hours, 44 minutes, therefore, seven hundred hours a day will not be very convenient for a person. Although you can accelerate the satellite by colliding it with comets and asteroids, but this is the last thing.

Well, if you come up with it, then on the terraformed moon there will be much more cool buns. For example, if you make the Moon with the oceans, then the Earth will act on them in the same way as the Moon on the Earth. That is, the ebb and flow will begin on the moon with waves under 20 meters - extreme and expanse for surfers.

In general, much on Earth is small because of the weight limit. If you put twice as many people on the bus, then its axles may not withstand and it will break. On the Moon, it is possible to increase the mass to such an extent that at least three-decker buses can be created, while three or four meters wide and about ten in length. Or make cars of the same size, but at the same time much less fuel will be spent, because the frictional force is much less than on Earth.

Your character will be able to see trucks with phenomenal carrying capacity on the Moon, bridges with fewer supports, taller buildings and bolder architecture - for example, the bulging parts of houses will become more massive, as the load on the structures becomes less.

However, there are disadvantages. There is very fine and light dust on the moon. Small winds will instantly raise whole storms that carry microscopic particles that are clogged literally everywhere. Including the lungs. Look how much dust the lunar car raises during the Apollo 16 mission:

The funny thing is that this rover on Earth weighed about 210 kg, which is only a couple of tens of kilograms more than an astronaut in a spacesuit. And on the surface of the moon, he cuts quite easily. During earthly trials, he did not manage to climb the bumps like that.

Well, like everything that came to mind. If you have any questions, please refer to the comments to the question.

You should pay attention to the video footage shot during flights to the Moon, where you can see how a person moves under lunar gravity.

Answer 3
July, 2021

Read the story of Isaac Asimov "The Gods Themselves", in addition to the fact that the author painted perhaps the most realistic and interesting life on the moon, it is also an incredibly smart and talentedly written story, an example of truly SCIENTIFIC fiction. It will be useful if you are a beginner author yourself and want to work in this genre.

Answer 4
July, 2021

Probably, first you need to read how science fiction writers describe human movements in low gravity. View astronauts' footage on the moon. In general, the movements of a person who grew up on Earth, with low gravity, will be very awkward.

You also need to bring air to the moon, it is difficult to run in a space suit.
