Mechanical Implications of the Teleportation of Rigid Extended Bodies from the Perspective of Classical Mechanics and Mathematics

Abstract

We develop a rigorous framework for the kinematics of a material point whose trajectory contains a jump discontinuity, modeled as a smooth curve on an interval punctured at one instant, with finite one-sided limits of position and velocity. A position jump is called an instantaneous teleportation. The event is treated as exogenous to Newtonian dynamics, imposed only before and after the removed instant. Separating the position and velocity discontinuities, we prove that the net linear impulse equals the momentum jump $\mathbf J=m\,\Delta\mathbf v$, carried entirely by the velocity discontinuity, while the position jump contributes none. This yields a \emph{momentum-compatibility} condition: an instantaneous displacement transfers no net impulse if and only if the velocity is preserved. For rigid bodies it splits into preservation of translational and angular velocity. For the rotating, revolving Earth, a kinematic fact governs the estimates: for two points of the same Earth at the same instant the orbital velocity cancels, bounding the jump by $2\omega R_{\oplus}\approx 9.3\times10^{2}\ \mathrm{m\,s^{-1}}$; the larger scale $6.0\times10^{4}\ \mathrm{m\,s^{-1}}$ arises only between orbital epochs or frames. The internal stress depends on how momentum is delivered, and the implied strains lie outside linear elasticity, so the figures are indicative.
