kinetic (adj.)youdaoicibaDictYouDict
"relating to motion," 1841, from Greek kinetikos "moving, putting in motion," from kinetos "moved," verbal adjective of kinein "to move" (see cite).
Buster Keaton's subject was kinetic man, a being he approached with the almost metaphysical awe we reserve for a Doppelgänger. This being was, eerily, himself, played by himself, then later in a projection room, watched by himself: an experience never possible to any generation of actors in the previous history of the world. [Hugh Kenner, "The Counterfeiters," 1968]
