So, one thing we said last time was when we put up a model and try and draw lessons from it, we should just take a step back and say, what's missing here?
在上一讲,当我们,从一个模型中总结结论的时候,我们应该回过头重新审视一下,看看我们是不是疏漏了什么
Conversely, if you get an answer and it doesn't seem to make sense, then you've got to go back and ask, am I violating some of the assumptions, and here you will find the assumption that the particle had that acceleration a is true as long it's freely falling under gravity but not when you hit the ground.
反过来说,如果你得到一个结果,发现似乎是错的,那么你就应该回过头来问问自己,我是不是违反某些前提了,这个模型中,你就发现,只要质点在重力作用下自由下落,质点具有加速度a的前提是正确的,但是落地后就不成立了
