Where does gravitational energy come from

Report as

The gravitational *force* is created by any object with mass. The more mass an object has, the more more gravitational force it exerts on other objects with mass. For objects that are spherical and uniform, the gravitational force points to the center of the object. For all other objects, it gets more complicated.

The gravitational "energy" is the energy that an object gains when you lift it against the gravitational force. Strictly speaking, the energy does not come from gravity, but from you pushing against gravity. For instance, when I lift a book high in the air, I have given it gravitational energy. The energy did not come from the earth, but from the muscles in my arm. When I let go, gravity converts this gravitational potential energy to kinetic (motional) energy as the book falls.

it always comes from the center of the mass of an object.

actually, this is incorrect. It comes from magnetic pulls from outside of our earth, that circulate the core.

So the sun's gravity comes from the earth?
