Do a stretched spring and a box on a high shelf both have potential energy why or why not explain you answer?

The correct answer to this question is "Yes." A stretched spring and a box on a high shelf both have potential energy. P otential energy is energy reserved to do work. Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched.
