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还有动和势。

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

基本上这个转换成所谓的势。

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，认为主要借助于重力势。

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

现在，们可以计算她在这一点上的重力势。

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

们有动、势和摩擦力。

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。

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 一段时间内的改变因此 一段时间内的改变。

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，将势转换回电。

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

认为这部分因为势已经证明了它非常有效的。

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

这两种技术都赌注押在势上，将其作为为电网储存可再生源的解决方案。

But potential energy isn't the only possible solution.

但势并不唯一可的解。

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。

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

这通过给水额外的重力势来储存。

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

在这种情况下，们的会被描述为势，对吧？

It also at this point has potential energy due to its gravitational position.

此时它还具有由于重力位置而产生的重力势。

Inside every battery, energy is stored as chemical potential energy.

在每一块电池内部，都以化学势的形式储存。

(ice shattering) As a timely delivery of potential energy from the Acme Corporation.

（冰层碎裂声）作为及时传递自Acme公司潜在的手段。

Where we put potential energy on one side.

们潜在的放在一边。
