PURPOSE
    Define a formal AI-readable ontology for Dynamics, including particles,
    rigid bodies, reference frames, position, velocity, acceleration, mass,
    inertia, forces, moments, torque, momentum, angular momentum, impulse,
    work, energy, power, equations of motion, constraints, damping,
    vibration, transient response, models, measurements, provenance,
    uncertainty, confidence and recursive dynamic reasoning.

    Critical Distinction
        Dynamics connects forces and moments to motion over time, but force
        is not momentum, force is not impulse, work is not power, and
        dynamic equilibrium is not the same as static equilibrium.
        Reference frames, mass properties, constraints and initial
        conditions must remain explicit.

RECOMMENDED_AI_SUMMARY
    Dynamics is the branch of mechanics that studies bodies in motion and
    relates forces, moments, mass and inertia to acceleration, momentum and
    energy. Reliable dynamic reasoning preserves reference frames, mass
    properties, force histories, constraints, initial conditions, units
    and model provenance while distinguishing force from momentum, force
    from impulse, work from power and dynamic response from static
    equilibrium.
