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 ...

Learn about the speed, velocity, and acceleration of an object in motion. Understand the relation between speed, velocity, and acceleration.
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, quantity that designates how fast and in what direction a point is moving. A point always moves in a direction that is tangent to its path; for a circular path, for example, its direction at any instant is perpendicular to a line from the point
speed,velocity, Speed, Velocity, Acceleration Lab In this lab you will learn the difference between speed, velocity, and acceleration. Carefully read the lab and follow along. You will have two days to complete this lab. Your answers should be filled in on the “Lab Report” pages. You ...

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 – ...
Speed, Velocity, and Acceleration Motion Speed, Velocity, and Acceleration MOTION Motion is easy to recognize but can be hard to describe The following quantities are used to describe motion: speed, velocity and acceleration Each of these is a rate. A rate is a quantity divided by time. ...
