Now, the purpose of this exercise is to give you a little bit of practice in figuring out what these quantities are.
就有这样的结论,这个练习的作用时让你们理解,这些物理量是什么。
Were you guys surprised by anything that you found when you actually printed out the final details?
当你们把最后的结论打印出来时,你们有没有对自己的发现感到惊讶
That's the result you use all the time in mechanics.

I got to confess to you that Socrates doesn't quite conclude the way I'd have thought he would have concluded, so I had the arguement conclude 6 the soul can't be destroyed.

I think you can tell by analogy with what I did in one dimension that the position of that object at any time t is going to be the initial position plus velocity times t plus one half a t square.
你们可以类比一下我在一维情况下的结论,这个物体在任意时刻 t 的位移,等于初始位移,加上 v ? t + 1/2 ? a ? t^2
