What is the acceleration due to gravity in a vacuum?

Answer 1

Yes. Gravity is a fundamental force that is the attraction between any object. It has nothing to do with pressure or gases.

Note that while some people may explain that it acts between two masses, and while this is true, it also affects light particles which have no mass.

Currently gravity is described as an effect on the space-time-continuum. Just imagine a heavy ball on a trampoline, but in 3D space rather than the 2D surface of the trampoline. A body with mass will create a sort of 'dip' in space which an object will fall into, including light.

are you talking about sub atomic particles ? and do you agree that outer space is a vacuum ?

and so what holds us to earth ? Earth has it's own atmosphere and the pressure inside that atmosphere is what holds us to Earth ! It is not magnetism !

Now as we venture into space , we ask what are "Black holes"

To understand this , we must think of outer space, as Flat !!

Then we can bigin to understand the Paradox of "Black Holes"

Answer 2

A gravitational field exists in the vacuum of space (empty space) and inside every material object in the universe.

There is no known way to create a gravitational field shield. By all scientific evidence, a gravitational field permeates all matter and vacuum and all space with no inhibition.

The only caveat in this is that a proper description of gravity requires General Relativity and the structure of space-time itself is modified by mass. In General Relativity, gravity itself is the curvature of space-time. That line of discussion gets one into the category of more-than-you-wanted-to-know.

Answer 3

Just super. Gravity doesn't require any medium to work in. The gravitational forces

between the sun and planets, and between the Moon and Earth, do a fine job of

maintaining the respective orbits, even across millions or billions of miles of vacuum.

Answer 4

The acceleration due to gravity depends only on how much mass

is in the neighborhood and how close you are to it. Your physical

environment ... like being surrounded by gas, immersed in water,

or hiding under the blankets ... has no effect on it.

In a vacuum chamber on Earth, the acceleration due to gravity is

9.81 meters per second squared. (rounded)

Answer 5

Gravity doesn't depend on the presense of air. It depends only on the masses ("amounts of matter") involved, and their distance.

Answer 6

The acceleration due to gravity in a vacuum is approximately 9.81 m/s^2. This value represents the rate at which objects accelerate towards the center of a mass in the absence of air resistance.

Answer 7

Nothing. Its weight remains the same.
