Spring Potential Energy Calculator
Spring Potential Energy is intended for the specific mechanics task described by its name. Enter spring constant n per m, spring compression or extension m to calculate a result expressed in joules. The formula works entirely in your browser and needs no account or external API. Only for linear elastic spring deformation. This estimate is useful for comparing scenarios when the supplied measurements follow the stated assumptions.
How to use this calculator
- Measure spring constant n per m in the units indicated on the input label.
- Enter Spring compression or extension m.
- Read the joules result, then compare alternative inputs to evaluate your own situation.
Spring Potential Energy formula
0.5*spring*stretch*stretch (joules).
- The expression 0.5*spring*stretch*stretch combines Spring constant N per m, Spring compression or extension m. Follow the units on each input: the answer is expressed in joules.
- Only for linear elastic spring deformation.
Worked examples
Worked example: Spring Potential Energy
Use these sample measurements: Spring constant N per m = 250, Spring compression or extension m = 0.1.
Compute 0.5*spring*stretch*stretch.
Using the example inputs, the result is 1.25 joules. Use this value to verify the formula before changing the measurements.
Understanding the result
Interpret the output as joules; it is not a measurement taken directly from a physical system.
Only for linear elastic spring deformation.
Important notes
Only for linear elastic spring deformation.
Review the input units, any required legal or engineering rules, and unusual edge cases before acting on this estimate.
Frequently asked questions
