elastic potential energy

Elastic potential energy is the stored energy in an object when it is stretched, compressed, or deformed elastically—that is, it can return to its original shape. Think of a stretched rubber band: when you pull it, you're adding energy, which is stored in the band’s elastic structure. If released, that energy converts back into motion, causing the band to snap back. This energy depends on how much the object is deformed and its material properties. Elastic potential energy is common in devices like springs and rubber bands, enabling them to perform useful work when released.
