So potential energy you might kind of remember from high school physics.

你们可能还记得高中物理里的势能。

When a thing is up at a height, it has stored potential energy.

当物体处一定高度时，它储存了势能。

Yeah, so it relies a lot on I suppose gravitational potential energy.

对，我认为主要借助势能。

It's a physics toy that demonstrates angular momentum, potential energy, and kinetic energy.

个物理学家的玩具可以演示角动量还有动能和势能。

The three levels of physics are different based on fulcrum, potential force, and resistance force.

物理学的三个层次根据支点、势能和阻的同而同。

The challenge for science was learning how to unleash this potential energy in a controlled way.

科学界面临的挑战了解如何以一种可控的方式释放这种势能。

I think this partly because potential energy has shown itself to be pretty efficient.

我认为这部分因为势能已经证明了它非常有效的。

But potential energy isn't the only possible solution.

但势能并一可能的解。

Basically converting this energy into what's called potential energy.

基本上就把这个能量转换成所谓的势能。

Both techniques are betting on potential energy as a solution for storing renewable energy for the grid.

这两种技术都把赌注押在势能上，将其作为为电网储存可再生能源的解决方案。

This stores the energy by giving the water extra gravitational potential energy.

这通过给水额外的势能来储存能量。

Now let's go back to potential energy in capacitors.

现在让我们回到势能和电容器。

In this case our energy would be described as potential energy, right?

在这种情况下，我们的能量将被描述为势能，对吗？

So there's excess potential energy that then can be used to raise those blocks  at height.

因此，有多余的势能可用将这些块提升到高处。

Then, when it's needed he blocks are released, spinning a turbine which converts the potential energy back into electricity.

然后，当需要的时候，这些块被释放，旋转一个涡轮机，将势能转换回电能。

We talked about electric potential energy and how it differs from electric potential, or voltage.

我们讨论了势能，以及它与 电延迟或张。

Instead, renewable energy is used to lift heavy block of concrete up into the air where it becomes potential energy.

相反，可再生能源被用来将沉的混凝土块提升到空中，在那里它变成了势能。

If the book is on this shelf, we can use this shelf as the 0.4 potential energy.

如果书在这个架子上，我们可以用这个架子作为0.4的势能。

When this happens, all  the kinetic energy of the fluid is converted into potential energy, in other words, pressure.

当这种情况发生时， 流体的所有动能都会转化为势能，即压。

So the potential energy depends on what type of charges there are, and how far apart they are.

因此，势能取决电荷的类型以及它们之间的距离。
