Calculate spring force and energy online

Hooke’s-law force = kx; stored energy = ½kx². Use this to check the stated relationship with your own numbers. The labels define the expected input order and units; the example provides a reproducible calculation.

How to use it

Enter exactly 2 comma-separated numbers in this order: spring constant newtons/metre, extension metres. Choose Calculate and review the result. Copy or download the output when it matches your requirements.

Worked examples

Use this to check the stated relationship with your own numbers. The labels define the expected input order and units; the example provides a reproducible calculation.

Reproducible sample

Settings: No additional settings.

Input:

100, 0.2

With the settings above, the output is:

Output:

{
  "forceNewtons": 20,
  "energyJoules": 2
}

For this input, “forceNewtons” is 20; “energyJoules” is 2. These are the named fields in the example output.

Limitations and common mistakes

Ideal linear spring within its elastic range; ignores preload and material limits.
Use the stated input order and consistent units. Decimal notation uses a dot; commas separate values. Results use floating-point arithmetic unless the tool explicitly says exact integer.

Frequently asked questions

How can I check the result?

Run the fixed worked example with the documented settings, compare its output, then check your own input format and units before copying a result.
