The nature of gravity is that a pair of equal attracting forces exist between every pair of masses, whose strength depends on the product of the masses and the distance between their centers..
Contrary to what many people believe, gravity is not caused by the rotation of the Earth. Gravity appears to be a universal property of matter which makes all objects attract one another. So gravity makes the Sun attract the Earth and the Earth attract its Moon. Gravity also makes the Moon attract the oceans on the surface of the Earth, making the tides.
The main reason a moon doesn't crash into its host planet and a planet doesn't crash into its local sun is this: each body is moving around its orbit at a speed that is just fast enough to produce an "outward" force that exactly balances-out the "inward" force of gravity which acts between the two bodies.
(Sorry. Wrong. balanced forces result in straight-line motion, and motion in a curved path does not produce an outward force. Try again.)
Another explanation
How does gravity work? How does magnetism work?
Energy can not be created or destroyed. To have energy you must have substance. The substance that causes gravity flows through the 'empty' space inside and in between all atomic particles. Collisions in between matter and the substance that causes gravity (aether) are infrequent, if not impossible.
It is not visible because light does not affect it, sort of how light passes through water. You can not feel it because it is more fluid than any gas. You can see it in solar flares, or when you pick iron pyrite out of the sand with a magnet and watch the iron dance on top of a paper plate while you hold the magnet underneath. A magnetic field is a constant supply of energy that is not potential, but creates kinetic force. Since there is kinetic response without any physical exchange, there must be substance. I call it spirit (wow did I just prove that divinity exists in the universe as a monist state?).
Event horizon is caused by reverse buoyancy effect. A black hole spinning very fast has a close undertow, and when something gets close enough, it is swallowed up. The more mass (atomic particles) an object has, the greater the effect it will have on the aether. Aether moves from positive to negative, or top to bottom, around and around, in and out. This explains why some galaxies have a jet effect. It effects metal (magnetism) because metal has shared electrons. Shared electrons allow current to flow, which explains why power sources can cause phenomena. It is effected by the motion of electrons. Neural pathways also effect this substance, this is why a shark can sense if an organism is living or dead from feet away. The closer to the center of an object you become, the higher the density of mater, and of aether. The higher the pressure of matter, and aether. Reverse buoyancy occurs, causing objects with mass to fall.
Furthermore, an object with less mass is held in orbit by an object with more mass because the larger object has a greater effect on the aether. Velocity also does effect orbit though, this is why the moon is not floating over the same area of the Earth all the time. It is relative.
Suggestion from an impartial observer: Use the first answer for information,
and the second answer for entertainment.
from the greek word PHYSIKOS which means ''natural'' and PHYSIS MEANING ''nature''.
The force of gravity is greater for objects with more mass.
Gravity is a natural force that causes pairs of objects to be pulled together.
Mass and newtons
The answer is that the two characteristics that affect gravity are mass and newtons. There is less gravity on the moon than on the earth. A space suit weighs 180 pounds on earth but on the moon it weighed way less than it was when it was on earth.
Known as a hygrometer. May be as simple as a few beads of differing specific gravity in a glass tube with a rubber bulb on top or a complex electronic device that determines specific gravity through measurement of other characteristics. A battery hygrometer uses floating beads to determine the charge of a lead acid battery because the specific gravity of the electrolyte will vary for a given state of charge.
No, gravity only pulls them together in the case of two objects. But, with three, gravity can launch one object away from the orbit of the other two. Therefore we can infer that gravity is dependant on the characteristics of the "reaction" not the individual "reactants".
Yes! It is even measurable. Einstein was the first to suggest this mathematically, and scientists have since proven this experimentally and in the real world - thus the discovery and identification of Black Holes in space. Gravity has the ability to bend light waves (thus begging the question - is light energy or matter - and thus described as both photons and waves. Photons would suggest characteristics of matter, and waves suggest characteristics of energy.)
Sorry; there is no line between gravity and no gravity. Gravity is everywhere.

gravity and temperature; It needs gravity so it can hold its atmosphere.
I think the answer of the international gravity returns to the atomic characteristics of materials and the basilar forces between the atoms that has been unknown up to now.
Gases are not restricted by gravity, so the molecules fly around, rather than stick together.
They all do have gravity, an axis, and all revolve around the sun.
northern lights here between exosphere and mesosphere gravity and air pressure decrease
Mass and gravity are directly connected, and luminosity is closely related to mass.
