Extended Classical Mechanics (ECM): Empirical Framework, Experimental Alignment & Structural Synthesis

This paper consolidates several empirical and observational findings that align with the conceptual framework of Extended Classical Mechanics (ECM). It examines gravitational dynamics in large-scale astronomical systems, phase evolution in rotating piezoelectric structures, and the behavior of electrons, holes, and photons in material systems through the common perspective of apparent mass and energy transformation. The work explores how frequency-dependent processes, inertial dynamics, and energetic redistribution may provide a unified interpretation of phenomena traditionally treated separately in gravitation, solid-state physics, and electromagnetic emission. Rather than serving as a formal derivation of ECM, this paper functions as an experimental and observational alignment study, highlighting domains in which ECM concepts may offer explanatory value and motivate further theoretical and empirical investigation.
