How to use the Linear Spring Energy Calculator
Measure extension or compression from the unloaded equilibrium position. A negative displacement represents compression but stores the same energy for the same magnitude.
The calculation
Worked example
A 200 N/m ideal spring displaced 0.1 m stores 1 J and has force magnitude 20 N.
Assumptions and limits
Valid only within the linear elastic range of the entered spring. Preload, damping, yielding and nonlinear stiffness are excluded.
