We have like kinetic energy, we have potential energy, friction.

我们有动能、势能和摩擦。

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。

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

对，我认为主要借助势能。

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

基本就是把这个能量转换成所谓的势能。

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。

And now, we can compute her gravitational potential energy at this piece.

现在，我们可以计算她在这一点的势能。

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

是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。

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

科学界面临的挑战是了解如何以一种可控的方式释放这种势能。

So, E from gravity is mass times gravity times height, which I get here to be 822 joules.

势能是质量乘乘高度，我这里得到的是 822 焦耳。

But potential energy isn't the only possible solution.

但是势能并是唯一可能的解。

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

我认为这部分是因为势能已经证明了它是非常有效的。

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

现在让我们回到电容器中的势能。

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。

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。

Finally, a flowing fluid also has the potential energy that comes from gravity.

最后，对流动的流体 势能来自。

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？

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。

And at the same time, its potential energy decreases, keeping its total energy the same.

时，它的势能在减少， 这使总能量保持变。

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，将其作为为电网储存可再生能源的解决方案。
