is gravity relative to us or a constant throughout the universe?

Answer 1

be careful, gravity is constant throughout the universe according to Newtonian physics,

the acceleration of gravity is relative to our earthly placement

Answer 2

For the moment, the force of gravity is proportional to the product of two masses divided by the square of the distance between the centers of the masses. In math talk that's F = GmM/R^2; where m and M are the two masses, R is the distance between their centers, and G is the constant of proportionality.

So the answer is, the force of gravity is relative to the masses and distances between them But there is a constant of proportionality (G); so in that sense, it is constant throughout the universe...maybe. By the way, G does show up in the theory of relativity; so it has its place as a constant even in relativistic terms.

As one answerer has already indicated, anomolies in gravitational effects on the Pioneer spacecraft may, that is MAY, indicate that perhaps G is not really constant afterall. [See source.] Futhermore, if we consider black holes as parts of the universe, then we have little clue (other than theory) whether our laws of physics remain valid inside them. Which means any one or all of the four fundamental forces of our universe, including gravity, may not exist or operate as otherwise specified in our normal universe.

But this is conjecture at this point; so, for the moment, we will presume that G really is constant. Indeed, gravity is not well understood; there is yet much to learn about it.

Answer 3

Not only is it a constant relative to mass, but there is a theory now that even dark matter which makes up most of the so called empty parts of the universe has a type of gravity of its own. So the answer is that it is indeed everywhere

Answer 4

Gravity is caused by the atraction between 2 objects, like the earth and the moon, or the earth and you, or the moon and you. As you get farther from the object the attraction decreases. The larger the object, the greater the attraction.
There are many places in the universe where you will be weightless, no gravity effect on you. There is less attraction between you and the moon, so you would weigh less there.

Answer 5

It depends on the mass of the planet you're in.

There is a gravitational constant G used in calculating how much forces between bodies in space.

But this constant is just a constant of proportionality between the force and the product of the two masses and the inverse of the square of the distance between them.

Answer 6

Gravity depends on the mass of the body. For example, on Earth, a falling object will accelerate 9.8 meters per second every second, while on the moon, 1.62 meters per second per second. Better than on Jupiter, which has a gravitational constant of 24.79 meters per second per second, which is about 2 and a third gs.

Answer 7

THat's acutally a good question.

So far we assume that the gravitational constant is the same all over the universe, but there are some things that are currently unexplainable that MIGHT point to fluctuations.

Answer 8

It is prevelant throughout the universe but is related to the size of the objects in question. Smaller planets have a smaller pull on objects.

Answer 9

Gravity is determined by the mass of the object that creates it.

Answer 10

The gravitational pull of any object is relative to it's mass. It is a constant.
