Summary

Some directional relationships between forces and accelerations in special relativity have been studied by considering the most general case of a body havingx, y andz components of velocity, which is acted upon by a force with nonzero components. The behaviour ofa y/ax anda y/az vs. velocity for different force component ratios is studied in the general situation in whichv xv yv z. It is shown that one or two, suddenly varying, negative acceleration components can result for the body at sufficiently high velocities, and an explanation is given.

Riassunto

Si sono studiate alcune relazioni direzionali tra forze e accelerazioni nella relatività ristretta considerando il caso più generale di un corpo con componenti di velocitàx, y ez, che è sottoposto a una forza con componenti diversi da zero. Si studia il comportamento dia y/ax ea y/az rispetto alla velocità per diversi rapporti tra componenti di forza, nella situazione generale in cuiv xv yv z. Si mostra che uno o due componenti di accelerazione negativi, a variazione improvvisa, possono risultare per il corpo a velocità sufficientemente alte, e se ne dà una spiegazione.
