Absolute Space, Laws of Motion and Universal Gravitation
The classical source of force, inertia, action-reaction and long-range attraction: the physical vocabulary that Identity Engineering adapts for Mass, Gravitation and binding.
In the Scholium to the Definitions of the Principia (1687; English: Mathematical Principles of Natural Philosophy) Newton distinguishes absolute space and time from relative, apparent ones. Absolute space is, by its own nature and without regard to anything external, always similar and immovable. Absolute motion is the translation of a body from one absolute place into another.
Newton's famous bucket argument is meant to show that true (absolute) rotation can be distinguished from mere relative motion by the appearance of centrifugal effects. Absolute space is therefore not only a mathematical convenience; it is the arena in which true forces and true accelerations are defined. Whether that arena must be a substance independent of bodies was already contested in Newton's lifetime (see Leibniz).
These laws supply the classical vocabulary of force, mass, acceleration, inertia and long-range attraction. They remain the baseline language in which later physics (and Identity Engineering's geometric primitives) still speak, even when the ontology of space itself is revised. Methodological caution: Newton's mass is a physical quantity in a dynamical theory; Identity Engineering's "Mass" is an engineered analogy that reuses dual roles (resistance and source), not a claim that identity obeys F = ma as physics.
- Mass: Newton's mass is both inertial resistance and gravitational source. Identity Engineering adapts the dual role: Mass resists incoherent change of the Stem and simultaneously curves the reachable region of configuration space so that other identities feel attraction.
- Gravitation: the long-range, always-attractive interaction between high-Mass coherent Stems is the direct analogue of Newtonian gravity. It remains the dominant interactive force in the current public framework.
- Action-reaction and force: every owned act that changes one identity's geometry exerts a reciprocal influence on the relational field. This underwrites the engineering discipline of measuring and designing mutual influence, without claiming exact physical equality of "action and reaction" in social systems.
- Limits and extension: pure Newtonian gravity is only attractive and long-range. The proposed Particles layer therefore adds Strong Binding (ultra-short-range coherence) and Electromagnetism (polarity, repulsion, fields, radiation) so that identity interaction is no longer one-dimensional. See Particles of Identity and Energy Forms of Identity.
Differentiation: Newton supplies the force language and the gravitational interaction. Identity Engineering keeps the language while rejecting absolute space as the primary ontology (preferring Leibniz's relational order) and while expanding the force inventory beyond gravity alone. The mapping is deliberate isomorphy work, not a claim that identity is classical mechanics.

Newton is the classical source for Mass and Gravitation in the framework. For the contrasting relational ontology of space see Leibniz. Multi-force extension beyond pure gravity is developed as a proposal in Particles of Identity and Energy Forms of Identity.
