I multiply both sides with R squared.

两边都乘以R的平方。

But now notice, I can substitute now for this v squared, I can substitute the square of this that is the orbital speed and then I get M G over R.

现在注意我能,代替这个v平方，我能代入这个平方,那是轨道速度,然后得到MG在R上。

So instead of being equal to negative z squared, now we're equal to negative z effective squared times r h all over n squared.

这里不再等于-z的平方，现在我们等于-有效的z的平方,乘以RH除以n的平方。

And we plug in our values and end up with mv squared mv^2/r-Ze^2/ over r minus Ze squared over And I am going to call this equation two.

我们最后的结果,就是,我把这称为方程式二。
