and how does the austronaut's space ship stay in place? don't use big vocabulary please. Not very good with big words...

there is gravity on the moon - just less than earth's. However, the moon rotates and stays in place because of earth's gravitational pull. Earth stays in place/ does it's rotations because of the sun's gravitational pull. The astronaut stays in place by the gravitational pull of whichever object it's rotating - using rockets to blast from one to the other. And as extra info here - The moon's gravitational pull controls the sea tides here on earth.
Hope that cleared things up for you!

Orbits are the outcomes of a ideal stability between the forward action of a physique in area, which includes a planet or moon, and the pull of gravity on it from yet another physique in area, which includes a great planet or celebrity. An merchandise with somewhat some mass is going forward and desires to maintain going forward; besides the undeniable fact that, the gravity of yet another physique in area pulls it in. there's a non-quit tug-of-conflict between the only merchandise wanting to bypass forward and away and the different wanting to tug it in. those forces of inertia and gravity could be completely balanced for an orbit to take place. If the forward circulate (inertia) of one merchandise is in basic terms too stable, the article will velocity previous the different one and not enter orbit. If inertia or momentum is plenty weaker than the pull of gravity, the article would be pulled into the different one thoroughly and crash.

There is gravity on the Moon just not as much as on Earth. If there was no gravity the space shuttle and astronauts wouldn't have been able to stand on the Moon. They would have immediately floated away.

THE MOON DOES NOT NEED TO HAVE GRAVITY TO SATAY IN THAT POSITION, THE MOON IS CONTROLLED BY THE EARTH, THE EARTH PROVIDES THE MOON A CENTRIPETAL FORCE THAT KEEPS THE MOON INTACT ALWAYS. IF WE TALK ABOUT THE GRAVITY OF MOON WE SAY DEFINETLY 'MOON DOES NOT HAVE GRAVITY' BUT YOU CAN SEE THE TIDE WAVES PRODUCED BY THE MOON.
THE MOON STAYS ON ITS POSITION BY THE MOVEMENT OF THE EARTH (as the earth makes gravity by rotating), SO THE FINAL CONCLUSION IS THAT THE MOON IS ENTIRELY CONTROLLED BY THE EARTH AS THE EARTH AND OTHER PLANETS IS CONTROLLED BY THE SUN. AN OBJECT DOES NOT NEED TO HAVE GRAVITY TO STAY OR ROTATE AT A PARTICULAR POSITION, AN OBJECT SHOULD HAVE THE SOURCE THAT MAY SUPPLY IT CENTRIPETAL FORCE...THANK YOU!

The moon stays in place because of Earth's gravity pulling it. It doesn't come at Earth though because it is too big for Earth's gravity to pull it. An astronaut's space ship stays on the moon because the space ship is so big that it weighs to much to be moved.

there is gavity on the moon, just very little
Every object has gravity, from very large to very small. It just doesn't have as much gravity as the earth, I think it's around 1/6, they why they stay on the ground and also that's why astronauts bounce when they walk, they weigh less and can't walk normally

If there is no gravity on the moon it doesn't stay in place

The gravity of the earth holds the moon.

Who told that there's no gravity on the moon? Newton's law of gravitation applies to ANY object with mass.

There is gravity on the moon, although it's only about one-sixth of the earth's.
