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

基本上就是量转换成所谓的势。

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

我们有动、势和摩擦力。

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

是物理学家的玩具可以演示角动量还有动和势。

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

你们可还记得高中物理里的势。

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

对，我认为主要借助于重力势。

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

现在，我们可以计她在一点上的重力势。

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种势。

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

当物体处于一定高度时，它储存了势。

Which means change in potential energy of an object over time is negative velocity times force.

因此 一段时间内总量的改变量因此 一段时间内总量的改变量。

But potential energy isn't the only possible solution.

但是势是唯一可的解。

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

我认为部分是因为势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.

两种技术都赌注押在势上，将其作为为电网储存可再生源的解决方案。

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，些块被释放，旋转一涡轮机，将势转换回电。

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

现在让我们回到电容器中的势。

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

在种情况下，我们的量将被描述为势，对吗？

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

通过给水额外的重力势来储存量。

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，在那里它变成了势。

It has the potential energy to wipe out the planet.

它有着摧毁整地球的潜在量。

It could kill us because it's using up all the chemical energy on earth and we contain some chemical potential energy.

它我们杀光是因为它要用完地球上的所有化学量了，而我们体内蕴含着一些潜在的化学量。

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

最后，对于流动的流体 势来自重力。
