What type of energy is stored in springs, a bow and arrow, or stretched elastic?

The type of energy stored in springs, a bow and arrow, or stretched elastic is elastic potential energy. This form of energy is associated with the deformation of an elastic object. When you stretch or compress an elastic material, like a spring or a bowstring, energy is stored in that object in the form of potential energy. This energy can be released when the object returns to its original shape, causing it to do work, such as propelling an arrow or causing a spring to push an object upward.

Elastic potential energy is specifically relevant in situations where an object can return to its original form after being deformed, which is the case for springs and elastic materials. Understanding this type of energy is essential when studying mechanical systems involving elastically deformed objects and their ability to perform work due to their return to equilibrium.
