## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/calculator/impulse-calculator/?solveFor=impulse&impulse=50&force=100&time=0.5

## Inputs
- solveFor: Solve for; type=select; required; default=impulse; values=impulse|force|time
- impulse: Impulse (N·s); type=number; required; default=50
- force: Average force (N); type=number; required; default=100
- time: Time interval (s); type=number; required; default=0.5; min=0.000001

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

## Formula
impulse J = average force F × time interval Δt

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