Kinetic Energy Calculator mechanism

Model scope

The formula is valid under classical, nonrelativistic assumptions. The verdict is NEEDS_REVIEW because the speed regime and input units are unspecified. honest_label='n/a' does not disclose the classical approximation or required SI units; an honest label should identify this as a classical/nonrelativistic translational kinetic-energy calculator.

• KE=½mv² is the correct classical formula for translational kinetic energy when mass is constant and speed is nonrelativistic.
• The spec does not state the nonrelativistic applicability limit; at speeds approaching the speed of light, relativistic kinetic energy must be used instead.
• The spec does not constrain mass to nonnegative values or clarify whether velocity may be signed; velocity may be signed because it is squared, but mass must be nonnegative.

Units and conventions

• Mass is in kilograms (kg).
• Velocity is in metres per second (m/s); the output is in joules (J).
• If supplied in other units, mass and velocity must be converted before applying the formula: 1 g=0.001 kg and 1 km/h=5/18 m/s.

Failure boundary

BREAK_CLAIMED · SELF_FLAGGED

The plain JavaScript arithmetic overflows for mass = 10^308 and velocity = 10^308, producing Infinity instead of a finite representable result. The unspecified velocity unit also permits materially different interpretations.
