§10 · electron force, work, and closing scope

Follow the introduction and all ten sections, including field transformations, finite light complexes, moving mirrors, charge-current transformations, and the electron-force conventions.

Newly authored explanatory preview in modern notation, with editorial and physics review pending. Both the kinematic and electrodynamic halves are treated, but this is not a German transcription, an aligned translation, or a complete critical edition. The source paragraphs, footnotes, acknowledgment, and date-lines are not claimed to be fully represented or reviewed here. Headings and argument units are editorial.

A force-to-acceleration ratio needs two frame labels

The printed transverse coefficient compares comoving force with laboratory acceleration and equals mγ². Using laboratory force with laboratory acceleration instead gives mγ. These are different definitions, not two conflicting values of invariant mass.

The work integral has an observable endpoint

Integrating the longitudinal force gives kinetic energy mc²(γ − 1), not the total rest energy. Accelerating voltage and curvature provide separate experimental relations under specified fields.
