Elastic potential energy calculator to find the potential energy of a stretched/compressed spring for a given spring displacement and spring constant.
Elastic potential energy formula is PE_{el}=1/2kx^{2}
The unit of spring constant is N/m, displacement is m and energy is Joule.
Note: Use dot "." as decimal separator.
