It's a physics toy that demonstrates angular momentum, potential energy, and kinetic energy.
是个物理家的玩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的势能。
When a thing is up at a height, it has stored potential energy.
当物体处于定高度,它储存了势能。
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。
The challenge for science was learning how to unleash this potential energy in a controlled way.
科临的挑战是了解如何以种可控的方式释放这种势能。
Which means change in potential energy of an object over time is negative velocity times force.
因此 间内总能量的改变量因此 间内总能量的改变量。
I think this partly because potential energy has shown itself to be pretty efficient.
我认为这部是因为势能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势能上,将其作为为电网储存可再生能源的解决方案。
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的势能。
But potential energy isn't the only possible solution.
但是势能并不是唯可能的解。
In this case our energy would be described as potential energy, right?
在这种情况下,我们的能量将被描述为势能,对吗?
This stores the energy by giving the water extra gravitational potential energy.
这通过给水额外的重力势能来储存能量。
Then, when it's needed he blocks are released, spinning a turbine which converts the potential energy back into electricity.
然后,当需要的候,这些块被释放,旋转个涡轮机,将势能转换回电能。
It has the potential energy to wipe out the planet.
它有着摧毁整个地球的潜在能量。
Now let's go back to potential energy in capacitors.
现在让我们回到势能和电容器。
It could kill us because it's using up all the chemical energy on earth and we contain some chemical potential energy.
它把我们杀光是因为它要用完地球上的所有化能量了,而我们体内蕴含着些潜在的化能量。
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的混凝土块提升到空中,在那里它变成了势能。
Anyway, this is all just to say that the change in potential energy is negative F times the change in position.
负的F(力的大小)乘以位置变化量有负号是因为 如果你让这个力直推着你。
So there's excess potential energy that then can be used to raise those blocks at height.
因此,有多余的势能可用于将这些块提升到高处。
We talked about electric potential energy and how it differs from electric potential, or voltage.
我们讨论了势能,以及它与 电延迟或张力。
