Will his average velocity help us to make correct iteration plan?
他的平均开发速率能够帮助我们制定准确的迭代计划吗?
And now we will look at the average velocity in a somewhat different way.
下面考虑下平均速度,方法就有些不同了。
So the signs in the velocity and the signs in average acceleration depend crucially on how I have defined my increasing value of x not where I choose my zero points.
所以速度的符号,和平均加速度的符号,这二者都取决于,这里x正方向,是如何定义的,和0点的选取没有关系。
I would expect, whether you're a Red Sox fan or not, you to be able to look at a list of different pitchers and their average velocity for their fastball, and tell me who has the longest or the shortest wavelength.
无论你是否是一个红袜队球迷,我预想你会看到一系列,不同的投手和他们,投出快球的平均速度,告诉我谁有最长的,或者最短的波长。
So, the average velocity may not tell you the whole story.
平均速度可能无法描述整个运动过程
So it's useful to have the average velocity.
平均速度还是很有用的
