Explanation:
Potential energy is present in a spring because the spring is elongated and some work is done it to elongate it.
The elastic potential energy present in a spring is given by [tex]kx^{2}[/tex]
where [tex]k[/tex] is the spring constant.It may vary from spring to spring and [tex]x[/tex] is the displacement of the spring from its equalibrium position.
It is evident from the equation that potential energy in the spring increases as [tex]x^{2}[/tex] increases.
