中文詞源
velocity 速度
來自拉丁語volo,飛，詞源同volatile,volley,引申義極快的速度?；騺碜岳≌Zvehere,攜帶，運(yùn)載，詞源同vehicle.
英英釋意
- 1. distance travelled per unit time
英文詞源
- 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.
同義詞辨析
speed, rate, velocity, pace
這些名詞均含"速度，速率"之意。
speed： 普通用詞，指單位時(shí)間內(nèi)行進(jìn)的固定速度或速率，也指可能達(dá)到的最高速度。
rate作"速度"講時(shí)，與speed同義，可換用。作速率解時(shí)，指相對(duì)增長(zhǎng)的速度，也指兩種相比較而得出的標(biāo)準(zhǔn)速度。
velocity： 技術(shù)用詞，指物體沿著一定方向運(yùn)動(dòng)時(shí)的速率。
pace： 普通用詞，指步行的速度，常引申指活動(dòng)的進(jìn)度或生產(chǎn)率。
