He says they represent a force which opposes what is happening inside Iraq.

So I'm going to solve this by enumerate and check, which is an example of what's called a brute-force algorithm.

你懂的,所以我得靠列举和检验来解决这个问题,这就是我们说的穷举算法。

To find the force, what you will do is, suppose somebody says, "Hey, I've got a new force.

为了找出这些力,你们要做的是,假设有人说,"嘿,我发现了一种力

We know what an electric field is, it's just a space through which a Coulomb force operates.

我们知道，电场不过,是库仑力的作用空间。

So, Newton did not ever tell you what the expression for force is in a given context.

牛顿从来也没有告诉过你,在这种情况下力的表达式

So, if we think about the force that occurs between a positively and a negatively charged particle, what we have is essentially a Coulomb force, so we can describe this as a force of attraction.

一个带负电的粒子之间，的作用力,这本质上就是库伦力，我们可以把它，描述成一个引力。

A typical problem that you may have done in your first pass at Newton's law, someone tells you a force of 36 Newtons is acting on a mass of whatever, 4 kilograms; what's the acceleration?

在你们第一次接触牛顿定律时,可能见过这么一道典型题目,告诉你,一个 36 牛的力,作用在一个物体上,4 千克吧,问加速度是多少

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？

We don't know what the force is, because we are hoping to say force is going to be m times a.

我们不知道力有多大,因为我们希望力是 m 和 a 的乘积
