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 = distance an object travels / time from start to finish Whichever way it is written, the answer is still the same! Let's look at an example. What is Velocity? Calculating Velocity Lesson Summary Register to view this lesson ...
First, add up the time to get 1 hour total. Also add up the distance: 5 + 5 = 10 kilometers. Finally, replace in the formula to get 10 / 1 = 10 km/h (kilometers per hour) on average in total. Average speed vs Average velocity ...
