## Use
Open the calculator page and enter values. Query-string parameters can restore and bookmark a calculation.
Example: https://askcalculators.com/calculator/impulse-momentum-calculator/?mass=2&initialVelocity=5&finalVelocity=15&time=0.2

## Inputs
- mass: Mass (kg); type=number; required; default=2; min=0
- initialVelocity: Initial velocity (m/s); type=number; required; default=5
- finalVelocity: Final velocity (m/s); type=number; required; default=15
- time: Time interval (s); type=number; required; default=0.2; min=0.000001

## Outputs
- impulse: Impulse Δp (N·s); format=number; primary
- initialMomentum: Initial momentum (kg·m/s); format=number
- finalMomentum: Final momentum (kg·m/s); format=number
- averageForce: Average force (N); format=number

## Formula
J = Δp = m(vf − vi); average force = J ÷ Δt

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