speed就是指速度,是一个比较非正式的口语化单词velocity是一个专业词汇,一般学过物理的都知道v表示速度,这里的v就是velocity的缩写,v是一个矢量,当然是同时表示方向和速率,可以总结为velocity = speed + direction... 分析总结。 speed就是指速度是一个比较非正式的口语化单词velocity是一个专业词汇一般学过物理...
Speed and velocity are both terms used to measure an object's movement; however, although some people use the words interchangeably, they are in fact different. Speed and velocity are often found in formulas used in physics, so it's important to understand that difference. Answer and Explanatio...
velocity是速度，包括速率。没有方向，标量speed也是速度，但有超速，迅速，加速，推进的意思。是有方向的。矢量
Answer and Explanation: Speed and velocity are two different terms but also has some things in common. First is that, both of them are used to measure an objects change of position. Second, is that the two of them also use the same measurement units that is meters per second. To underst...

Velocity is a physical vector quantity The units associated with velocity is important in physics. Learn about the SI unit of velocity, formula and other common units.
What Is Velocity? Ok, here's where the confusion sets in: velocity and speed are similar, in concept. Like speed, velocity is equal to the distance you travel divided by the time it takes to reach a destination. Confused? Don't worry about it and here's why: ...
