In more high an object gets more energy. How?

things like to happen, and anything that can happen probably will. But lots of things can’t happen, like a ball spontaneously rolling up a hill or an electron decaying into an antiproton.
An object with “excess” energy can spontaneously lose that energy in various ways — it can give off radiation, eject a piece of itself, or smack into something at rest and give it some kinetic energy. An object with a deficit of energy is really stuck in that state until something comes along to supply that energy.
This is pretty explicit in quantum field theory: we draw all the Feynman diagrams that don’t violate conservation laws or symmetry principles, and then we can calculate the relative probability of each process; some are more probable than others, usually because they are governed by stronger interactions or there are more different ways they can happen. But anything that can happen will (or might) happen eventually “all by itself” unless something else happens first.
In Newtonian Mechanics we talk about gradients of potential energy as forces, which makes this process seem more personal and intuitive. (He forced me to do it!) But it’s still the same reason that cable TV providers charge so much: “Because they can.”
