Angular Momentum Calculator implementation

Binding contract

This record describes what an executable surface must bind and validate. It does not claim that a public calculator, package, or production route is deployed.

Input and validation requirements

The conservation calculation is undefined when I2 = 0. A plain-arithmetic implementation may return +Infinity instead of rejecting the input, so zero-denominator validation is required.

Required corrections

No binding erratum is attached to this unique-name record. Implementers must still preserve the declared units, domain, and failure behavior.

Inspectable interface fixture

The sample below is evidence for interface and validation tests, not a production implementation.

{
  "inputs": {
    "mode": "angular_momentum",
    "I": 3.2,
    "I_unit": "kg·m²",
    "omega": 2.5,
    "omega_unit": "rad/s"
  },
  "expected_outputs": {
    "L": 8,
    "L_unit": "kg·m²/s"
  },
  "working": "L=Iω=3.2 kg·m² × 2.5 rad/s=8.0 kg·m²/s."
