Acceleration and velocity are both vectors.加速度和速度都是矢量。 velocity 速度来自拉丁语volo,飞,词源同volatile,volley,引申义极快的速度。或来自拉丁语vehere,携带,运载,词源同vehicle. velocity (n.)early 15c., from Latin velocitatem (nominative velocitas) "swiftness, speed," from velox (genitive velocis) "swift, speedy, rapid, quick," of uncertain origin, perhaps related to vehere "carry" (see vehicle), or from the same root as vigil." |
