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和。

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

基本上就是把这个量转换成所谓的。

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

你们可还记得高中物理里的。

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

对，我认为主要借助于重。

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上的重。

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

我们有动、和摩擦。

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、和阻的不同而不同。

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

科学界面临的挑战是了解如何以一种可控的方式释放这种。

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

当物体处于一定高度时，它储存了。

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

重是质量乘重乘高度，我这里得到的是 822 焦耳。

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，将转换回电。

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

我认为这部分是因为已经证明了它是非常有效的。

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上，将其作为为电网储存可再生源的解决方案。

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

相反，可再生源被用来将沉重的混凝土块提升到空中，在那里它变成了。

But potential energy isn't the only possible solution.

但是并不是唯一可的解。

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

这通过给水额外的重来储存量。

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

现在让我们回到电容器中的。

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

在这种情况下，我们的量将被描述为，对吗？

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

最后，对于流动的流体 来自重。

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

我们讨论了，以及它与 电延迟或张。
