Gravity is the force of attraction between all objects with any mass. This applies to planets and stars and particles of dust as well. This attraction is extremely weak and is dependant of the mass of each item and the distance between them squared. (I.e. by moving twice the distance gravity falls to 1/4 of the original). The distance is measured from the centre of each mass.
Therefore gravity on the moon which is approximately 1/6 the weight of the earth is approximately 1/6 that of earth.
When we are on the surface of the world if we fly higher there is a very small change in gravity as we have moved away from the earth but relative to the diameter we have only moved a very small percentage.
Gravity is a constant and applies for the whole universe.
The only place where gravity appear to go a little strange is black holes where the force of gravity is so large even light is bent and cannot escape. Little is really known about black holes.
In essence gravity is not a gas, or made of anything but is a force between any 2 objects. As much as gravity attracts you to the ground the ground is attracted to you.
When we are in space and orbiting around the earth we are moving along and in constant free fall but as we move fast enough after we have dropped we have also gone round the world and so will keep on falling. Satellites and the like do eventually fall to earth as they are slowed down by the very thin atmosphere in space and once slowed do eventually fall down and burn up.
Hope this helps good question
This doesn’t explain what gravity is MADE OUT OF. This explains what it DOES.
I am in search for an answer for WHAT it is – I already know what it does.
Thanks.
So what is magnetism made out of?
what is the force that drives it made out of?
i want to know too.
even air has some kind of chemical make-up.
:l
There is no way of creating gravity. B/c we really don’t know what its made of. Black holes have so many nuetrons an numerous other things that we could not create the density levels to obtain gravity, such as a black hole does. and even if we could the area would have to be as big as the sun in our solar system. you would have to be able to smash Mt. Everest into a rock the size of your hand to create the density inorder to even start to understand gravity or black holes.
Gravity is made of mass. No mass. No gravity.
Mass has a natural affinity for mass. The attraction works in much the same way that tiny bubbles in a liquid (the medium) tend to merge into larger bubbles — with the difference being that the medium of gravity is the relative vacuum of each atom’s most interior space.
In a somewhat wry, McLuhan-esque way: The medium is the mass-age.
