Potential energy storage refers to the ability to store energy in a system based on its position or configuration. Common examples include gravitational potential energy, where energy is stored when an object is elevated above the ground, and elastic potential energy, found in stretched or compressed materials like springs. These forms of energy can be released to perform work when the object returns to its original position. In addition to mechanical systems, potential energy storage can also be found in chemical energy, where energy is stored in the bonds of molecules. Batteries, for instance, store energy chemically and release it as electrical energy when needed. This versatility makes potential energy storage crucial for various applications, including renewable energy systems and everyday devices.
