If there is no gravity in space, how do rockets land say on the moon?

Answer 1

WHO IS SAY ? I HAVE NEVER HEAR'D OF THEM, AND WHY DO THEY DESERVE TO GO TO THE MOON HUH..

Answer 2

All objects with mass have a gravitational field, which includes the moon. These fields extend into space. This is how the planets end up orbiting the sun. The further away from the source of a gravitational field an object is, the less attraction there is.
Gravity is actually a very weak force. Consider that all the mass of the earth powering the earth's gravity, can be overcome by a very small magnet!

Answer 3

Gravity is calculated by the size of the planet the larger the planet ( or ball of stuff) the more pull it has, the sun being the greatest and the moon being one tenth of that of earth. Its like in the star wars books where animals from higher gravitatonal planets become excellent fighters on those with less since they are so much stronger.

Answer 4

There is a gravitational force acting on any object of mass and an attractive gravitational force acting between any two or more objects of mass (Newton's Laws).

The moon is an object of mass, as is a spacecraft. Therefore it does "have gravity" and spacecraft can land on the moon without changing the laws of physics, Captain.

(The gravitational force acting on the moon is about one sixth the strength of the one on earth, which is why people float in between steps on the moon)

Answer 5

All bodies have a gravity. Even you have a small gravitytional field but it is overpowered by earths gravitational field. In space there also is gravity but since many gravitational fields overlap in interplanetary and interstelar space those are close to nullified. Closing in on one body (e.g. the moon) you get more and more if its gravitation. In all the moon has about 1/6 of earths gravitational field. In fact there are very little points in space where the gravitational field of moon and earth exactly level out resulting in no gravitational force.

Answer 6

There is gravity on the moon but it is about 1/8 of the earth. Every mass has a force of gravity and an attraction to another object, even u to ur chair and stupid q's it seems like. The smaller the mass the smaller the attraction till mostly its not noticeable.

Answer 7

There is gravity on all bodies in space (including the Moon).

Answer 8

Everything in the universe exerts its own gravitional force, even YOU are exerting a gravitational pull on the earth as you are. The only thing is that bigger objects have a larger pull and their effects are more obvious, so the earth pulls you towards it much much much stronger than you pull it towards you. So, the moon's gravity is what makes it possible for objects to orbit it, land on it and move around on it. As an aside, the moons gravitational pull is a sixth of the earths, as its six times smaller.

Answer 9

The moon is not space. The moon has gravity and attracts things that go near it. If the moon did not have gravity then the sea tides would not happen.

To avoid crashing into the moon you need to fire retro rockets to slow yourself down. There is no atmosphere so parachutes or wings are not an option.

Answer 10

The greater the matter of an object the bigger the force on it causing gravity (thats why a pencil doesn't have a very big force and the sun does) There is no matter in space, but there is in the moon.

DOH! How old are you? Im 12.

Answer 11

Gravity is made by bring 2 heavy objects near each other and applying electricty to one of them, and spinning the other.

As the moon is already spining all that is needed is to carry a heavy weight (say 15 kilo's of cheese, which is quite a lot and will give you nightmares) and to electrify the spaceship when it gets close to the moon.

This is what makes mars so hard to land on, as it dosen't spin, either it has to be electrified (difficult) or large magnets are needed to hold spacecraft down.
