Introduction to the Energy Shuttle: The "Energy Shuttle" is a demonstration exhibit that can vividly display the process of mutual conversion of potential energy and kinetic energy, thereby revealing that "all materials in nature have energy, and energy can neither be created nor created. It cannot be destroyed, but can only be converted from one form to another, and transferred from one object to another. During the process of energy conversion and transfer, the total amount of energy remains constant." This law of energy conservation.
