Max Planck, who introduced his quantum theory in year 1900, used the electronic circuit model of the atom for the derivation. The hydrogen atom consists of a single electron and a single proton. Obviously, gravity is an electric phenomenon. My own investigations have shown that there is an excellent correlation between the Coulomb forces between two hydrogen atoms and the force of gravity between them. For more details you can do an internet search for the book: "The Secret of Gravity".
It is gravity that holds our Sun together, it keeps our spinning EARTH in orbit around the sun and holds objects on the earth's surface. The gravitational field is much like that of as electrical field charge since their fundamental laws are inverse square laws. Therefore there is a "gravitational potential" between any two masses. Because the Earth is so much larger than anything on it, it seems that we are only being pulled toward Earth..... But we are actually being slightly pulled toward everything with mass in accordance with the gravitational potentials.
gravity causes objects to fall
It is the gravity pull of the moon and the gravity pull of the sun that causes tides.
gravity does
Matter causes gravity in the first place.
Gravity mostly
wind water gravity and ice
Gravity causes air to be denser near Earth's surface.
Gravity causes the ships iron anchor to sink to the ocean.
Earth is hafly big, so it has gravity. Larger, it has more gravity. Smaller, it has less gravity.
