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
A curved slope means that the acceleration is changing – the object has non-uniform acceleration. Check carefully whether a graph is a speed-time graph or a distance-time graph. On true speed–time graphs, the speed has only positive values. On velocity–time graphs the velocity can be...
planes and automobiles. These equations can also be applied to more complex problems like the speeds of sound and light, the velocity of planetary objects and the acceleration of rockets.
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 ...

Acceleration like velocity has two aspects, both magnitude and direction. When something falls under gravity near the earth's surface, it falls through the air. This causes friction that, if the falling object is large, reduces the acceleration. If falling with its plane vertical, a piece of ...
