As you stretch or compress a spring, the force varies, but it varies in a linear way (because in Hooke’s law, force is proportional to the displacement).
Potential energy is stored energy that depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched.

Hooke's Law defines the force used to displace a spring as: F = -k*x. The minus sign conveys that this is a restorative force acting in opposition to the spring being stretched or compressed. And then we know that energy is defined to be the ability to do work, so there is a direct relationship between energy and work. This last formula reads: The potential energy of a spring, or the energy stored in a spring, equals one half times the spring constant times the square of the extension. This is how to calculate how much energy is stored in a spring. Work Done Compressing The Spring Some linear springs store energy through compression, rather than extension.
