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

基本上就是把这个能量转换成所谓势能。

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

我们有动能、势能和摩擦力。

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

是个物理学具可以演示角动量还有动能和势能。

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

你们可能还记得高中物理里势能。

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

对，我认为主要借助于重力势能。

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

现在，我们可以计她在这一点上重力势能。

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

科学界面临挑战是了解如何以一种可控方式释放这种势能。

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

当物体处于一定高度时，它储存了势能。

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。

But potential energy isn't the only possible solution.

但是势能并不是唯一可能解。

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。

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上，将其作为为电网储存可再生能源解决方案。

So these red blocks represent the potential energy.

因此，这些红色方块象征着势能。

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，将势能转换回电能。

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

现在让我们回到电容器中势能。

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

在这种情况下，我们能量会被描述为势能，对吧？

So it has potential energy, which is the energy associated with height.

因此，它具有势能，即与高度相关能量。

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

这通过给水额外重力势能来储存能量。

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

相反，可再生能源被用来将沉重混凝土块提升到空中，在那里它变成了势能。

It has the potential energy to wipe out the planet.

它有着摧毁整个潜在能量。
