Final answer:
Elastic potential energy is stored in a system when an object is deformed and can be described by Hooke's law. Examples of systems that store elastic potential energy are stretched rubber bands, springs, and pole vaulting poles.
Step-by-step explanation:
Elastic potential energy is stored in a system when an object is deformed and can be described by Hooke's law. One example of a system in which elastic potential energy is stored is a stretched rubber band. When a rubber band is stretched, it stores elastic potential energy that can be released when the rubber band returns to its original shape.
Another example is a spring. When a spring is compressed or stretched, it stores elastic potential energy. This energy can be released when the spring returns to its equilibrium position.
A pole vaulting pole also stores elastic potential energy. As the pole bends, it stores energy that can be released to propel the vaulter over the bar.
