Elastic energy examples

The information on this page is ✔ fact-checked.

Elastic energy refers to the potential energy stored in an object when it is deformed or stretched due to the application of a force. It is produced when an object undergoes elastic deformation, which means it can return to its original shape after the deforming force is removed. Objects possess elastic energy when they have the ability to store and release energy as a result of their elasticity. This energy is closely related to Hooke’s law, which states that the force needed to deform an object is directly proportional to the amount of deformation. When a force deforms an elastic object, such as compressing a spring or stretching a rubber band, elastic energy is stored within the object. This energy can be released and converted into other forms of energy when the object returns to its original shape. The ability of objects to store and release elastic energy is fundamental in various applications, from mechanical systems and structures to sports equipment and toys.

Examples

Resistance band

A resistance band is designed to provide resistance during exercises, and it demonstrates the principles of elastic energy. When a resistance band is stretched, the elastic material within the band undergoes deformation, storing elastic potential energy. This stored energy is released as the band is allowed to return to its original shape. The resistance band thus provides a form of resistance training, where the user works against the elastic force generated by the band. The controlled release of stored elastic potential energy contributes to muscle engagement and strength-building during various exercises.
