Gravity
One of the four fundamental interactions, gravity is responsible for the fact that any objects with mass attract one another. According to general relativity, it is a space time curvature, but according to quantum mechanics it is the result of exchanges of virtual gravitons.

When objects are moved further apart from each otherthe force of gravity between them?
" ... decreases."
Gravitational force is inversely proportional to the square of the distance
between the objects.
What is 4 things that gravity is caused by?
Gravity is only due to presence of core in earth's centre.
=======================================
Answer #2:
Gravity is a property/characteristic/attribute of mass and space that causes
forces of attraction between every two specks of mass in the universe.
The forces of gravitational attraction between two objects are determined by:
--the mass of one object
-- the mass of the other object
-- the distance between their centers of mass.
How do astronauts do experiments in space with zero-gravity?
Gravity is certainly not necessary in order to do experiments. In fact, there are
some experiments that can ONLY be done in zero gravity ... like for example an
experiment to determine how seeds decide which way to send roots and where
to extend the green shoots when there is no 'up' or 'down', or whether fruit-flies
can maintain their sanity in zero gravity and continue their important mating work.
What would happen to stars if there was no gravity?
If there were no gravity, period, there would be no stars. If gravity ceased to work, there would be a whole lot of violent explosions as the nuclear, mechanical and other forces within the stars popped the stellar balloons, so to speak.
That depends; what exactly do you expect such a "gravity machine" to do?
* Any mass will exert a force of gravity.
* Artificial gravity (an imitation of gravity) can be produced through quick spinning.
* Other types of "artificial gravity" appear in science fiction stories, but they don't appear in current technology, and it seems unlikely that they will be, any time soon.
What is meant by the term 'artificial gravity'?
The term "artificial gravity" refers to using science technology to create gravity. This is usually desired by astronauts and space organizations such as NASA to keep their astronauts healthy and to minimize the effects of weightlessness on astronauts during long term space travel.
Why is the force of gravity different on Pluto than earth?
Well, for one thing, because the Earth has abouit 50 times as much mass
as Pluto has. Mass has a big effect on the forces of gravity, you know.
What is the distance from earth where gravity becomes zero?
There is no such distance. Gravity has no limit. There are forces of gravity
between the lint in your pocket and the smallest grain of sand on the farthest
beach on the other side of the farthest planet, in orbit around the farthest star,
in the farthest galaxy from Earth. Of course, the farther apart two objects are,
the less the gravitational forces between them are. But the forces are still there.
Why moon is only the natural satellite of earth?
Because all other satellites orbiting the earth are man-made.
Where can one view a video about an air hog zero gravity car?
The most comprehensive site on the internet for viewing videos would have to be youtube. Simply visiting the site and typing into the search function, 'air hog zero gravity car' will bring you lots of results. The results cover reviews, demonstrations and advice on using it.
Where can one find Defying Gravity lyrics?
There are numerous websites that are dedicated to posting lyrics to songs including Defying Gravity. One can access the lyrics to this song on sites such as Metro Lyrics, Lyrics Mode and A-Z Lyrics.
-- 1 cubic meter of space is 1,000 liters of space.
-- 1 liter of water has 1 kilogram of mass.
-- 1,000 liters of water has 1,000 kilograms of mass = 1 metric ton
-- 1 metric ton of water fills 1 cubic meter of space.
-- A substance with a specific gravity of 2.7 packs 2.7 times as much mass
into the same space.
-- 2.7 metric tons of it pack into 1 cubic meter of space.
-- The number of cubic meters it occupies is (the number of metric tons)/2.7 .
-- For ANY substance, the number of cubic meters it fills is (the # of metric tons)/(specific gravity) .
Why is there no gravity outside your atmosphere?
There certainly is gravity outside the atmosphere. For example, it is gravity that keeps the Moon in orbit around the Earth, and the Earth in orbit around the Sun.
How can you reduce center of gravity for vehicles?
"Centre of gravity" is not a number, so you can't 'reduce' it.
Center of gravity is a place on the structure of the car. You can MOVE it lower
on the car by redesigning the car to move some of its mass downward. Like
for example: Mount the fuel tank under the car instead of on the roof. Store
the spare tire under the trunk instead of on top of it. Use bucket seats instead
of bench seats, so the passengers sit lower.
You could also lower the car's center of gravity by adding concrete blocks or
lead weights to it, down low on the frame. But increasing the vehicle's weight
in order to move the center of gravity is not too smart.
Does the center of gravity always have to be located withing an object?
No. The center of gravity of a wedding ring is in the space at the center of the ring.
The center of gravity of the letter ' V ' is somewhere along the vertical line between
the two slanted lines.
Is gravity falls coming back in 2013?
Yes. Gravity Falls is an animated Disney Channel Original Series created by Alex Hirsch. It was renewed for a second season by the Disney channel in March of 2013.
A character in Gravity Falls. Also Mabel Pines’s brother, Grunkle Stan’s nephew.
How much time less then gravity of the moon as compare to the earth?
moon's gravity is (1/6)th of the earth's gravity
Why there is zero gravity in space?
Actually there is gravity (non-zero gravity) in space. You just don't feel it when you are in free fall. For more details, read some articles (for example, in the Wikipedia) about "free fall".
What are the age recommendations for Air Hogs Zero Gravity toys?
Air Hogs Zero Gravity toys recommend that the user of their product be between the ages of 8 and 12 years old. The reason for this is small parts that may be swallowed by younger children.
Where can one find zero gravity chairs?
Walmart, Amazon, and the Oveerstock website all sell zero gravity chairs. There are many different types of "zero gravity chairs" so be careful which one you are ordering.
Is Saturn's gravity weaker or stronger than Earth?
Saturn's mass is 568,460*1021kg
Earth's mass is 5,973.6*1021kg
As mass effect gravity Saturn's gravity is stronger
Earth's gravity pull is 9.8ms-2
Saturn's gravity pull is 10.4ms-2
-Thunder-
Something to think about:
If Saturn's mass is 95 times as much as Earth's mass,
why is its gravity only 6% more ?
-Lightning-
Why is the world flat but round?
The earth's gravity field makes everything push into the earth like a bubble arround the planet. This makes it seem like the earth is flat.
