POTENTIAL ENERGY
This apple weighs 150 grams. Gravity on earth is 9.8. The height from the ground to the apple is 5 meters. Therefore PE=7350
This apple weighs 250 grams. Gravity on earth is 9.8. The heigh from the ground to the apple is 2.5 meters. Therefore PE=6125

CONSERVATION OF ENERGY
Energy cannot be created or destroyed, only changed from one form to another. That concludes the total amount of energy remains constant over time, even as it transforms between types.
Let’s assume this UFO is electric. There are chemical energy stored inside the battery of this UFO. The chemical energy converts to electric energy which flows through the UFO’s motor and converts into kinetic energy. None of this energy is lost (I know UFO do not run on motor or electric).
