## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/calculator/hookes-law-calculator/?solveFor=force&force=-20&springConstant=200&displacement=0.1

## Inputs
- solveFor: Solve for; type=select; required; default=force; values=force|springConstant|displacement
- force: Force F (N); type=number; required; default=-20
- springConstant: Spring constant k (N/m); type=number; required; default=200; min=0.000001
- displacement: Displacement x (m); type=number; required; default=0.1

## Outputs
- result: Solved value; format=number; primary
- unit: Unit; format=text
- magnitude: Magnitude; format=number

## Formula
Hooke’s law F = −k × x, with k = −F/x and x = −F/k

## Rules
- Empty optional inputs are undefined, not zero.
- Hidden conditional inputs are ignored.
- Do not invent missing required inputs.
