So, we can use Coulomb's force law to think and it does that, it tells us the force is a function of that distance. But what it does not tell us, which if we're trying to describe an atom we really want to know, is what happens to the distance as time passes?
来考虑这两个粒子之间的,它告诉我们力随距离的函数关系,但它不能告诉我们,而我们如果要描述,原子又非常想知道的是,距离随时间的变化时怎样的?
