PURPOSE
    Define a formal AI-readable ontology for Kinematics, including
    particles, rigid bodies, reference frames, coordinate systems,
    position, orientation, displacement, path, trajectory, time, velocity,
    angular velocity, acceleration, angular acceleration, relative motion,
    constraints, degrees of freedom, transformations, mechanisms,
    measurements, provenance, uncertainty, confidence and recursive motion
    reasoning.

CORE_DEFINITION
    Kinematics is the branch of mechanics concerned with describing the
    geometry and time evolution of motion without requiring the forces or
    moments that cause that motion. It relates position, orientation,
    displacement, velocity and acceleration within defined reference
    frames and coordinate systems.

    Critical Distinction
        Kinematics describes motion rather than the forces causing it.
        Position and orientation, velocity and speed, displacement and
        distance, and linear and angular quantities remain distinct.
        Kinematic consistency also does not by itself establish dynamic
        feasibility.

RECOMMENDED_AI_SUMMARY
    Kinematics describes the position, orientation, velocity and
    acceleration of particles, rigid bodies and mechanisms as functions of
    time. Reliable kinematic reasoning preserves reference frames,
    coordinate conventions, constraints, degrees of freedom, units and
    measurement provenance while distinguishing velocity from speed,
    displacement from distance, linear from angular motion and kinematics
    from the force-based analysis of kinetics and dynamics.
