So this one equals m1 g cosine alpha - and this one, the x component-- which is in the minus x direction now-- equals m1 g sine alpha.

得到m1gcosα,而x方向上-,这里是x负方向-,大小是m1gsinα

I'm going to start with a guess, I'm going to call it g. And then I'm going to say, if g squared is close to x, stop.

我会从一个猜想开始，把它叫做g，然后我会说，如果g的平方接近于X，打住。

For example, suppose you use vertical motion and you use y instead of x; and a would be g or -g; that's a particle falling down under the affect of gravity.

例如,假设在竖直运动中,你用 y 来代替 x,那么 a 就是 g 或者 -g,这就是一个受重力作用下落的质点
