PURPOSE
    Define a formal AI-readable ontology for Mechanics, including bodies,
    particles, reference frames, position, displacement, velocity,
    acceleration, mass, force, moment, torque, momentum, angular momentum,
    work, energy, power, equilibrium, motion, constraints, constitutive
    behaviour, statics, dynamics, kinematics, kinetics, models,
    measurements, provenance, uncertainty, confidence and recursive
    mechanical reasoning.

CORE_DEFINITION
    Mechanics is the branch of physics and engineering concerned with the
    behaviour of bodies under forces and constraints, including conditions
    of equilibrium and the relationships between position, motion, mass,
    force, momentum and energy.

    Critical Distinction
        Mechanics relates forces and moments to equilibrium and motion, but
        force is not momentum, moment is not force, velocity is not
        acceleration and work, energy and power are distinct physical
        quantities. Motion quantities must always retain their reference
        frame and units.

RECOMMENDED_AI_SUMMARY
    Mechanics is the branch of physics and engineering that studies bodies
    under forces and constraints, covering equilibrium, motion, momentum,
    work and energy. It includes statics, dynamics, kinematics and kinetics.
    Reliable mechanics reasoning preserves reference frames, coordinate
    systems, vector directions, units, constraints and assumptions while
    distinguishing force from momentum, force from moment, velocity from
    acceleration and work from power.
