## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/science/velocity-acceleration/?initialVelocity=5&acceleration=2&time=10

## Inputs
- initialVelocity: Initial velocity u (m/s); type=number; required; default=5
- acceleration: Acceleration a (m/s²); type=number; required; default=2
- time: Time t (s); type=number; required; default=10; min=0

## Outputs
- finalVelocity: Final velocity v (m/s); format=number; primary
- velocityChange: Velocity change Δv (m/s); format=number

## Formula
v = u + at

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