在日常用语中，这两个词没有区别，可以通用。而在物理学里，velocity 是一个矢量(vector quantity)表示起点与终点间直线距离的长度除以所用时间所得的量，并注明方向：而 speed 是一个数量(scalar quantity)，是指起点到终点所走过的所有路程除以所用时间所得的量，且不标明方向。
velocity是vector类型,而speed是float类型。它们都是速度的意思,但区别是什么? zhoujun681 兰州烧饼 10 一个带方向,一个只是单纯的值 断刀2014 兰州烧饼 10 vel应该是在3个坐标轴方向有分量的向量,speed应该是=|vel|,就是vel的绝对值,是floate lecreuset 1L喂熊 1 如果你要一个物体以 5.2 的Speed...

speed指运动的速度,既可指快速,也可指慢速; velocity表示沿一定路线运动的速度,通常指直线、弧线或圆周运动的速度,这个词可与speed通用,但多用于科学技术方面。一、velocity词汇分析音标：英 [vəˈlɒsəti] 美 [vəˈlɑ:səti]释义：速率，速度;周转率...
Like average velocity, instantaneous velocity is a vector with dimension of length per time. The instantaneous velocity at a specific time point $$ {t}_{0} $$ is the rate of change of the position function, which is the slope of the position function $$ x(t) $$ at $$ {t}_{0}$...
