And we've talked about it before when we learned about Coulomb's law.

我们之前在了解定律时已经讨论过它。

You could review Coulomb's laws videos in the physics playlist.

您可以在物理播放列表中查看定律视频。

Capacitance uses units of Farads, with one Farad equal to one Coulomb per Volt.

电容以法拉为单位测量，其中一法拉等 超过伏特。

The Mohr-Coulomb constitutive model is used to simulate soft soil.

莫尔-本构模型模拟软土。

And in both cases the constant is 9 times 10 to the ninth Coulombs.

在这两种情况下， 数都 9 乘以 10 到第九。

It’s just that, instead of using kilograms to find Newtons, here we’re using Coulombs to find Newtons.

只，这里我们不千克来求牛顿， 来求牛顿。

The charges we talk about when we talk about electrons and protons, those are the coulomb forces.

当我们谈论电子和质子时，我们谈论的电荷就力。

We also know the Coulomb constant equals the  inverse of the quantity four pi times the permittivity of free space.

我们还知道数等四圆周率乘以自由空间介电数的倒数。

For example, one electron has a charge of negative 1.6 times 10 to the negative 19th Coulombs.

一个电子的电荷为负1。6倍 10 次方减去 19 。

This whole expression is known as Coulomb’s Law. And k is often known as the Coulomb’s Law constant.

这整个表达式被称为定律。 k 通被称为定律数。

And k is often known as the Coulomb's Law constant.

定律。并且知道 K 定律数。

Now, let's put Coulomb's Law to the test!

或减去，取决吸引力或 不和谐；现在让我们把定律！

But to calculate the number of Newtons, we’ll first need to measure the charge, denoted by “q”, in units called Coulombs.

但要计算牛顿数， 我们首先需要测量电荷， “q” 表示，单位称为。

In this the fuel starts off in a small capsule and the Coulomb barrier is overcome by applying an external shock.

在这种情况下，燃料从一个小胶囊中开始，通过施加外部冲击克服势垒。

We also discussed Coulomb’s law and how the force between charged particles is calculated using vectors.

我们还讨论了定律以及如何使矢量计算带电粒子之间的力。

Or in the case of electrons, when they get further away from a high energy state, the coulomb force is weaker, right?

或者就电子言，当它们远离高能态时， 力会变弱， 对吗？

So we want to describe complex situations involving charged particles using more than just Coulomb's Law.

我们想描述复杂的状态，包括粒子 电荷，不仅定律。

To find F, you just have to use Coulomb's Law.

要计算 F，你只需要使定律。

In fact, you can plug the equation for Coulomb's Law into this equation, in place of capital F.

其实你可以输入一个定律方程 在这个方程中，代替了 F。

This value – the charge of a single electron in Coulombs – is known as the elementary charge, and it’s denoted with a lowercase “e”.

这个值——中单个电子的电荷——被称为基本电荷， 小写字母“e” 表示。
