## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/calculator/acceleration-calculator/?startVel=0&endVel=27.78&time=5

## Inputs
- startVel: Initial Velocity (m/s); type=number; optional; default=0
- endVel: Final Velocity (m/s); type=number; optional; default=27.78
- time: Time Taken (s); type=number; optional; default=5

## Outputs
- result: Result; format=text; primary

## Formula
Average acceleration = (final velocity − initial velocity) ÷ elapsed time.

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