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

是个物理学家玩具可以演示角动量还有动能和能。

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

基本上就是把这个能量转换成所能。

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

你们可能还记得高中物理里能。

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

对，认为主要借助于重力能。

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重力能。

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

们有动能、能和摩擦力。

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

学界面临挑战是了解如何以一种可控方式释放这种能。

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

当物体处于一定高度时，它储存了能。

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

因此 一段时间内总能量改变量因此 一段时间内总能量改变量。

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

然后，当需要时候，这些块被释放，旋转一个涡轮机，将能转换回电能。

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

认为这部分是因为能已经证明了它是非常有效。

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能上，将其作为为电网储存可再生能源解决方案。

But potential energy isn't the only possible solution.

但是能并不是唯一可能解。

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

相反，可再生能源被用来将沉重混凝土块提升到空中，在那里它变成了能。

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

这通过给水额外重力能来储存能量。

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

在这种情况下，们能量会被描述为能，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重力能。

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

在每一块电池内部，能量都以化学能形式储存。

(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公司潜在能量手段。

Where we put potential energy on one side.

们把潜在能量放在一边。
