Now we can calculate what the difference is between the potential energy... the kinetic energy after the collision and the kinetic energy before the collision.

我们可以计算出差别，在储存能量。，与碰撞后动能的差别，还有碰撞前动能。

The relationship and difference between electric potential energy, interaction energy and electrostatic energy are revealed through calculation and discussion of some examples.

通过具体例子的计算和讨论，揭示了静电场中的电势能、相互作用能和静电能之间的联系和区别。

What people did is they said let's define a unit of energy that represents a unit charge accelerated across a unit potential difference, and let's call that the electron volt.

前人们所做的就是他们说让我们确定,一个能量单位用来代表一单位电荷,加速穿过形成的一单位电势差，我们叫它电子伏特。

And the electrical energy is the product of the charge on the electron times the voltage which is the potential difference through which the electron was accelerated. And so this allows me to, by increasing the voltage, increase the energy on the electron.

电子能量是电子上的电荷数,乘以电压的结果,这是种内在的差距,通过它电子运动得以加速，这也让我，通过增强电压，来增加电子能量。

In the brain, the signals travelling through the synapses rely on action potential, which is the electrical energy created by the difference in concentrations of charged atoms (ions) on the inside and outside of neuron, which move back and forth through ion channels.
