What it calculates

The “Spring Potential Energy” calculator computes Spring energy in J from 2 parameters: stiffness k (N/m), extension (m).

A standard physics formula used in educational and engineering tasks.

Example calculation

With parameters Stiffness k = 200 N/m, Extension = 0.1 m the result is 1 J (E = ½·k·x²).
