Work-Energy & Impulse-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.

Effect

Computation or source lookup only

Input and validation requirements

Extreme finite inputs overflow the plain-arithmetic JavaScript Number representation to Infinity. The specification also leaves angle units, height reference direction, and gravitational acceleration convention implicit, producing materially different results for plausible interpretations.

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.
