The "substance" in atoms that creates gravity is mass. It is the mass of the protons, neutrons and electrons that create gravity. While the individual masses of these particles and even atoms and molecules are small, it is their collective mass that gives rise to the "larger" effects we see. So let's look. Gravity is actually looked at as a curvature in spacetime by physicists. But there is nothing wrong with the idea that any mass will attract any other mass via gravity. A person has mass, and that mass is attracted to the mass of another person. But this attractive force is small because of the "small" mass of the people. The earth, on the other hand, has a lot of mass compared to that of a person. And it will pull that person to its surface. The reason that one mass attracts another mass is because of gravity. Gravity is an extension of mass; anything with mass has gravity. Beyond that and beyond the idea that gravity is a curvature or "dent" in space time, we have to do a little head scratching. There are still some things to discover as regards the deeper mysteries of this, one of the four fundamental forces in the universe.
They're not related, and neither has any effect on the other.
Inertia does not affect gravity, these are two entirely separate things, even though they both are produced by the same thing, which is mass. Mass creates both inertia and gravity, but inertia and gravity do not affect each other.
No. They are two seperate forces. (But their actions on an object may add or subtract from each other.)
free falling is whena gravity is pulling a object or anything down and no other forces are acting on it.
Yes it does. It has mass and like all other objects it is attracted to other masses. Throwing a parachute out of a plane will demonstrate this. It will head for Earth.
Acceleration does not effect gravity. It is rather the other way round. Gravity can affect the rate of acceleration.
the suns gravity pull creates the earths movement as well as the other planets
electrons
It is really the other way round - gravity has an effect on weight. The more gravity, the more weight.
Because it just does
It keeps them in orbit
Gravity causes forces that attract every two objects in the universe toward each other.
They're not related, and neither has any effect on the other.
Inertia does not affect gravity, these are two entirely separate things, even though they both are produced by the same thing, which is mass. Mass creates both inertia and gravity, but inertia and gravity do not affect each other.
There is no effect to gravity due to earth fast spins because gravity is other thing and spin of earth is different thing. So we could not compare to each other. Gravity is made of mass of earth and spin of earth is due to sun, as earth revolving around the sun.
The multiplier effect, is when one job in the mining industry creates 4 new jobs in other industries
Mass is a property almost all matter has. It does not change from place to place, it is always constant. It is measured in Kg. Gravity is the effect mass has on other mass. It is the effect 2 (or more) bodies of mass drawn to each other. Gravity is measured in m/(s^2), this is a unit of acceleration.
