Spring Force and Energy Calculator
Calculate restoring force and elastic potential energy from spring stiffness and displacement.
Spring Force and Energy Calculator User manual
- Fill in the parameters or select the file according to the form, and check the unit and format first.
- A 100 N/m spring extended by 0.1 m has a force magnitude of 10 N and stores 0.5 J.
- Click the processing button to view the results, you can copy or download and save.
Calculation method and processing rules
Use Hooke's law with force magnitude k|x| and energy kx²/2. Positive displacement is extension; negative displacement is compression.
scope of use
Applies only within the linear elastic range. Yield, fatigue, preload and actual spring selection are not assessed.
Will the input content be saved on the server?
This tool handles input in the browser, and does not upload files or form content. Typing practice scores are only saved in the native browser.
Why may the result be different from other tools?
Applies only within the linear elastic range. Yield, fatigue, preload and actual spring selection are not assessed. Please compare the input unit, rounding method, applicable rules and data version first.
