Why is there not as much gravity in space as there is on Earth?

Answer 1

The force of gravity is dependent on two things:

The first is how massive the Earth is.

The second is how far you are away from the Earth.

The farther you get away from the Earth, the less force gravity exerts.

The farther you are from earth the less gravity there is.

Answer 2

Gravity is weaker in space because it decreases with distance from an object. While Earth has a strong gravitational pull due to its mass, objects farther away experience less pull. In deep space, where objects are far apart, the gravitational force is significantly weaker.

Answer 3

There isn't, necessarily. Some areas of space will have high gravitational fields, such as the area around a black hole.

But for the most part, most of space is low gravity (never can you be somewhere that's "no" gravity--that would require you to be existing an infinite distance away from the nearest object with mass, and, well, you have mass!) because of the inverse square law: the gravitational constant is already tiny, so you can only feel the presence of gravity when very close to a very massive object. If you go a long way away from a massive object, the field gets exponentially weaker.

Answer 4

There is gravity in space; it just isn't very noticeable. This is because the strebgth of gravity decreases by a large amount if the two objects are more distant - being twice the distance makes the force only a quarter as strong, being 5 times distant makes it only 4% as strong.
There is gravity in space. Objects in space seem weightless because they are in freefall. If you have ever gone skydiving, or bungee jumping, or even been on a rollercoast, you will have experiences a sensation of weightlessness during freefall.

Answer 5

Gravity is dependent on two variables; mass and distance. Our gravity on Earth is determined by the mass of the Earth and the radius of the Earth.

Gravity on the Moon is determined by the mass of the Moon (much smaller!) and the radius of the Moon (also smaller). It works out that the gravity of the Moon is about one-sixth the gravity of the Earth. Even in their massive space suits, the astronauts were able to leap several feet up. The Lunar Rover "space car" would have collapsed of its own weight on Earth; on the Moon, it was strong enough to carry two people AND a couple hundred pounds of moon rocks.

Answer 6

Gravitational pull between two objects follows a simple formula: G * m1 * m2 / r2. G is a constant, for this question it's not relevant. M1 and M2 are the mass of the two objects (traditionally in kilograms), which obviously don't change when you go into space - the Earth is made of just as much 'stuff' and so are you. However, the entire formula is divided by r2, which is the square of the distance between the center of the objects in meters. Dividing by the square of the distance means doubling the distance between the center of the objects divides their gravitational attraction by 4, and tripling the distance divides their attraction by 9; so on and so forth.

From sea level to the the Earth's surface is about 6378km, so 'r' in the formula is about 6378000. If you fly to 6378000 meters above the Earth, doubling 'r', the gravity between you and Earth is down to 1/4 what it was when you were standing on the Earth. The further you go away from large objects, the more the gravitational attraction continues to decrease.

As for 'why' this universal force exists or why its rules work the way they do, those are questions that have not yet been answered.

Answer 7

there is nothing around you that is big enough to pull you towards it. If you get close enough to a planet, you will get pulled into its orbit ( a bit like gravity) if you land, there will be some gravity because of the planet's gravitational pull.

Answer 8

The force of gravity is "mutual". That means it's always a pair of forces, acting

between two masses, pulling them toward each other, equally in both directions.

The strength of the force depends on the size of both masses, and on how far

apart they are from each other.

Based on that background, it should be pretty clear by now why the force on you,

your shoes, or the change in your pocket, should be a lot stronger when there's a

planet nearby (the Earth for example), than it is when the only mass near you is a

space ship, a fuel tank, or another person.

Answer 9

space did not have gravity because there is noting like gravity forcing you down and there is noting to force down

Answer 10

Gravity decreases with distance, so it is possible to be far away from a planet or star and feel less gravity.
