And often, if you want to make a lot of it, you have to think about the thermodynamics of the system, how fast the reactions will go and kinetics, and then whether they'll go, the thermodynamics, and sometimes then you need to adjust the reactions, maybe use a transition metal to make it go better.

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
