How is an apple falling from a tree like the potential difference in a battery?

While the apple is on the tree, it has potential energy. As soon as it begins to move, some of the potential energy is transformed into kinetic energy. When it falls down, the potential energy transforms more and more; shortly before the apple hits the ground, there is merely potential energy left, it all transformed into kinetic energy.

Explanation:

And always keep in mind, the potential energy doesn’t disappear Energy always just transforms
