what is the meaning of gravity?

Answer 1

It's the surface gravity that keeps you held down to a planet, otherwise you would free float. Surface gravity is what keeps the atmosphere and the water held to a planet too.

On Earth, the surface gravity is 0.5 to 2.0 Gauss. Which means the molten dynamo in the center of earth (again, think of it as a long bar magnet in a sphere) is at least 5,000 Gauss (1/2 Tesla) to 20,000 Gauss (2 Tesla). So if you landed on Mars or Ganymede, you would have to drill a shaft 1/2 way down and insert a stacked NeBFe Bar Magnet or Superconducting Magnet to increase the surface gravity. Then measure the surface gravity with a Gaussmeter and if it equals 0.5 to 2.0 Gauss, you could start pumping oxygen, carbon dioxide and nitrogen into this man made bubble. You wouldn't have to worry about floating away, or not having oxygen to breathe (of course you will need grass seeds and some soil).

In our Milky Way Galaxy there are 235 planetary bodies, of which 169 moons are in our Solar System. These 169 moons are the well documented satellite moons of the 9 planets. Jupiter alone has 63 moons. The challenge lies in how we can build atmospheres on them to support human life and all other living things. Also, we have to weed out the ones that are inhospitable.

Venus=0, Earth=1, Mars=2, Jupiter=63, Saturn=60, Uranus=27, Neptune=13, Pluto=3

The trick is to categorize them into planets/moons that either spin on their axis, or don't. Then, increase the surface gravity by inserting a Superconducting Magnet into the core. The magnet would range from 2 Tesla to 15 Tesla, depending on the amount of iron/nickel that is present in the core.

Finally, you would have to introduce atmospheric gases (nitrogen, oxygen, and carbon dioxide) into the man made electromagnetic bubble. Armed with this knowledge, we can build restaurants throughout our Milky Way Galaxy.

Answer 2

meaning of gravity? I don't understand the question?
If what you mean by that is what is gravity then it's the attractive force of an object with mass.
Ok, maybe I now understand...
The meaning or definition would be
the attractive force between 2 or more objects which compells them to accelerate closer together.
Or something like that

Answer 3

Einstein had no explanation for a cause of gravity, so I sidestepped the issue by say it is a property of space.

300 years ago Fatio and Lesage offered an explanation. I believe the Fatio/Lesage model is on the right track, but seriously flawed. I have come up with a number of modifications of my own. They postulated particles (classical gravitons) moving many times faster than light and pushing matter particles toward one another. I substitute p-waves in the ether, which are fused or split by matter.

Answer 4

Gravity is a force that holds everything on the surface of the planet and is held there because of whatever is going on inside the earth whether it is Solid or hollow that is another discussion.

Answer 5

gravity is what we call the force which pulls things down to the surface.

however in classical sense that is.

in the early 20th century people figured that gravity is the result of bent space, which means that every mass in 3D-space bulges space like a weight on a 2D-rubbersheet.

so every mass has a specific directional force onto other masses due to this effect.
this is what we call gravity

Answer 6

There are different types of gravity, but what holds us to the ground is the gravitational force between matter. Any two bodies or masses have a gravitational attraction to each other. This attraction or force is directly proportional to the mass or weight of the two (or more) bodies acting on each other. The larger the mass the larger the gravitational force it has. So the mass of our planet and the mass of our bodies, keeps us firmly planted on the ground. Larger people weight more as they exert more force when they step on the scales because of their bigger mass. No offense to bigger people.

Answer 7

Do you mean to ask what the 'definition' of gravity is? If so, I invite you to consult a dictionary. This will save you (and us) a lot of time.

Answer 8

look at the "farien" idiot get a god#amn degree corrupt mf

Answer 9

It has no meaning, it just is.
