how far do you have to be away from earth until there is no gravity anymore.?

Question

its just wierd cuz you can be super high in the sky and there could be gravity, and then if you move one mroe foot upwards there is none,, how does that work?

if you were on a larger plantet would the gravity be greater?

Answer 1

Planets, like Earth, are so big that they have a Centre of Gravity. It's located right in the centre of the planet, and everything around is drawn towards that spot. The farther you move away from the centre of gravity, the weaker it's pull is, until eventually you are completely uneffected.

Answer 2

I think you might be confused because you think there isn't any gravity in orbit (Like on the space station). This isn't true. I know this seems weird, but the Earths gravity is nearly as strong at the space station as it is on the surface of the Earth. Even as far away as the Moon it is still very strong. How do I know? Because it is the strength of the gravity that keeps both the space station and the Moon in orbit around the Earth! Without the Earth's gravity, both would fly off in a straight line and never come back.
It APPEARS that there isn't any gravity on board the space station because the station and everything in it is actually in free fall. It doesn't hit the ground because it is moving forward so fast that it actually falls AROUND the Earth.
As an example, if you were in an elevator at the top of a building, and someone cut the cable holding it up, both the elevator and you would begin to free fall. While you were falling (inside the elevator), you would float around just like they do in the space station. This doesn't mean there isn't any gravity, of course. It just means you are falling. Same is true in orbit. There is still gravity there, objects just appear to be weightless because they are falling around and around the planet. If the space station slowed down and stopped moving forward, it would fall out of the sky and crash to the ground.

Answer 3

Gravity is considered to be unlimited in range.
As you move away from the surface Gravity diminishes with the square of the distance.
Additionally,if you travel fast enough horizontally you will go into orbit and you would be,virtually gravity free.

Answer 4

That's not how it works. Gravity diminishes by the square of the distance. At some point it becomes negligible. Where that point is depends on your definition of "negligible", but there is always gravity.

Answer 5

There will always be gravity, it just gets weaker and weaker the farther away you get from the source.

Answer 6

gravity has no limits, but it became very weak....
and then the apport of earth's gravity can be smaller than other planets' gravity....or the sun's gravity...

Answer 7

well techinically theres always gravity just not nough to matter
after a few hunred miles theres almost no gravity

Answer 8

hm..well, actually I think there is gravity everywhere. It's just in some places there is more and in some places there is less.
