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。

Average speed vs Average velocity Average Speed formula The average speed calculation is simple: given the distance travelled and the time it took to cover that distance, you can calculate your speed using this formula: Speed = Distance / Time The metric unit of the result will depend on the...
