velocity作为名词，意为速度、高速，通常指直线、弧线或圆周运动的速度，多用于科学技术方面。speed可作名词和动作，意为速率、迅速、加速、促进，既可指快速，也可指慢速。例句扩展 velocity 作为名词，速度、高速 1.Thus,velocity is the team's capacity.因此，速度是团队的能力。2.Acceleration and velocity are ...
第一个，是我们最常的速度的意思，不需要精确计算第二个，一般是计算后的速度，所以数学和物理上常用，或强调一个正常，准确的速度概念时常用最后一个是加速度，当然不同了以上是我自己的总结，我认为就可以区别这三个词了，你还可以多参考其他答案 ...
Answer Speed = distance ÷ time Speed = 10 miles ÷ 15 minutes Speed = 0.67 mi/min Velocity = 0.67 mi/min South Acceleration Definition Formula Acceleration is a measure of how quickly the velocity changes Formula a = Dv/t What does the D mean? – The Greek letter D represents change. ...

Learn about the speed, velocity, and acceleration of an object in motion. Understand the relation between speed, velocity, and acceleration.
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...
acceleration是加速度, velocity是速度,speed是位移,知道意思应该就没问题了吧

Velocity–time and speed–time graphs A change of velocity is called acceleration. Speeding up, slowing down and changing direction are all examples of acceleration. Fig. 9.2 shows how to interpret a velocity–time graph. Image A positive slope (gradient) means that the speed is increasing – ...
