Answer 1

It is called Gravitational Potential energy.

At moon the gravitational potential energy is lower than earth,which is 1.6 newtons.

Answer 2

it is gravitational force which action to keep us ground on the surface of earth.
attraction of an object towards ground is called gravitational force and this gravitational force is due to the magnetic force of earth .
every object have its magnetic field so every object in earth attracts towards earth. And when we beyond its field means in space we started to fly because of zero gravity in space.
