Energiapäiväkirja 10. Potentiaalienergia

Translation: I don't understand potential energy. Has lifting supposed to have created potential energy? What about in space? Does potential energy exist when there is no gravity? Well... There are gravitational forces and many big objects pulling smaller objects to many directions. Is potential energy the same thing as having an opportunity to move?
