理解averagespeed和averagevelocity的差异，有助于我们更好地分析运动现象。首先，平均速率，即average speed，它代表的是物体在一定时间区间内通过的路程的平均值。计算时，我们只需将总路程除以总时间间隔，结果是一个标量值，没有方向性。而平均速度，average velocity，不仅考虑到位移的大小，还强调了方向...
average speed是平均速率，等于distance/time interval(路程/时间间隔），是一个标量，只有大小，没有方向。average velocity是平均速度，等于displacement/time interval(位移/时间间隔），是一个矢量，既有大小，又有方向。

What is the secret Its speed. If we could throw the ball hard enough it would go up and up forever and never come down. The speed at which it would have to be thrown to do this is known as escape speed. Of course, we cannot throw a ball hard enough because the speed required to...
