How astronauts walk on the moon?
The same as on Earth, only they have less mass, weighing an average of 45lbs, including suit. The danger is that your inertial mass does not change...this means that you could easily jump fifteen feet high or more on the moon...but you would still break your legs when you hit the "ground". Apparent weight changes with local gravity, but mass does not. being hit with a bowling ball would be exactly the same on the moon, or in space, as on earth. It would HURT.
The moon has a gravitational field strength which is 1/6 that of Earth's one, which means the astronaut's weight on moon would be 1/6 that on Earth, so the astronaut would be lighter on the moon, so he can literally bunny-hop on the moon.
