What you learn in Theory:
An object’s mechanical potential energy derives from work done by forces, and a label for a particular potential energy comes from the forces that are its source.
What you learn in Practice:
When the only work done on an object is performed by conservative forces, its mechanical energy remains constant, whatever motions it may undergo.
