Motion, Momentum and Energy

01Position of the module · Identity and Statement

Chapter 2 interprets inertia as the response to reconfiguring a localized material core and its accompanying spatial structure. LVE supplies motion-dependent scale factors. With an explicit inertial constitutive relation, integration gives total momentum, and force and work lead to dynamics.

These familiar forms have distinct premise chains in ASD. Momentum uses an angular inertial closure and mass normalization. Total energy additionally adopts $E_0=m_0c^2$ beyond the kinetic-energy integral. This module displays those steps explicitly.

02From LVE to calculable dynamics · Derivation Route

03Reading this module · Module Guide

• Inertia and Momentum: Eqs. (2.8)–(2.14), including the constitutive input between the directional factor and inertial response.
• Force and Work: Eqs. (2.15)–(2.21), longitudinal and transverse acceleration, and circular motion in a common local calibration.
• Energy and Action: Eqs. (2.22)–(2.24b), with explicit integration, rest-energy normalization and the free Lagrangian.
• Experimental Relations: Mathematical reproduction versus physical interpretation, and the relation of universal coupling in Eqs. (2.24c)–(2.24d) to observations.

04What matching mathematics means · Relation to Established Physics

Where quantities and configurations are aligned, $p=m_0\gamma v$, $E=m_0\gamma c^2$ and the free Lagrangian have the forms of standard relativistic dynamics. ASD constructs them from spatial structure and constitutive inputs. This route does not use a Lorentz transformation or a relativistic energy formula as a premise.

Mathematical form: same. Derivation route: different. Physical interpretation: different.

Matching mathematics does not independently establish ASD’s structural explanation. A different explanation does not itself create a numerical difference. Discrimination requires the output of a common apparatus calculation, as discussed in Experimental Relations.

05Domain and boundary · Domain and Limitations

The dynamical chain uses a core–accompanying-field system in a uniform reference background, with fixed internal state, no net radiative loss and $0\leq v<c$. Here $m_0$ is fixed, $t$ is the common reference counting parameter, and $c$ the local vacuum propagation speed.

The microscopic volume-density profile, inertial angular distribution, rest energy and universal coupling still require common matching to spatial dynamics and matter theory. Results are DERIVED under the stated constitutive relations, with CONDITIONAL mathematical review. Describing inertia as spatial does not replace those matching conditions.

This construction introduces no continuous drag-energy cost for free uniform motion. Radiation, internal excitation or a nonuniform background requires the corresponding additional energy and momentum terms.

06Sources and the gravity interface · Sources and Continuation

The module retains Chapter 2 §III’s core derivation and the counting convention of §I. Microscopic closure is concentrated in OP-DYN-01 (Chinese) · Chinese original. LVE v1.1’s mathematical review conditions remain upstream dependencies.

The current Gravity module develops background scale functions, light deflection, Shapiro delay, orbits and static compact-object exterior models. It uses these motion relations and adds its own background-scale and coupling inputs. The inertial closure here does not replace those conditions or calculate microscopic particle masses.
