but let's keep friction out

但我们不考虑摩擦
because I'm trying to do something different here.

因为在这里尝试些新的东西
So, you want to know what these guys will do now.

你想要知道这些物体现在会怎么运动
So first guess is, well, M looks so impressive compared to small m,

先初步猜测 M 看起来要比 m 大得多
so maybe it'll go downhill.

所以可能它会沿斜面向下滑动
But I realize that's of course fallacy because M is a symbol;

但我意识到了这显然是错的因为 M 只是个符号
the value associated with it maybe 1/10th that of m.

其实它的值可能只有 m 的十分之一
But if M really is bigger than m,

但就算 M 的值真的大于 m
then am I assured it'll go downhill?

那我就能肯定它会往下滑吗
The mass has to be greater.

那质量必须更大
Pardon me?

你说什么
No, no, I'm saying, if the big mass M is bigger than the small mass m,

不不我是说如果 M 的质量比 m 大
