Elastic potential ID$|$ Problem

The equation below shows the mathematical representation of$$spring potential energy$($also called the elastic potential energy$)$ of an object that is being acted upon by a$$linear ideal spring$$with a spring constant, k $($also called the stiffness of the spring$).$ A linear ideal spring either$$pushes or pulls $($that is$,$ it responds with$$a$$restoring force$$of$$equal strength in either case$)$ in direct proportion $($k$)$ to the distance it is either compressed or stretched away from its equilibrium position $($also called its "relaxed length"$).$Match each term in the equation with the correct description from this list:

$(1)$ Spring Constant;$$

$(2)$ Distance from Equilibrium;$$

$(3)$ Spring Potential Energy
