The energy of motion is called kinetic energy.

运能叫做能。

When it's let go, it turns into kinetic energy.

当它被释放时，它就变成了能。

Temperature is a measure of those atoms' kinetic energy.

温是那些原子能。

Faster motion increases the kinetic energy of the molecules and atoms.

更快运速导致了粒子能增大。

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还有能和势能。

Then we made machines that used kinetic energy from water and wind.

后我们又造出了利用风能和水能机器。

Wind turbines convert the kinetic energy of the wind into mechanical power.

风力涡轮机将风能转化为机械能。

As the tyres bounce they convert kinetic energy into heat, thus wasting it.

由于轮胎对挤压力反弹，能传化为热能浪费。

The more kinetic energy there is, the heavier these daughter particles can be.

能越大，越能更大质粒子。

This kinetic energy depends on the mass of the object and how fast it's moving.

这个能取决于物体质和它移速。

Temperature is really a measure of all that jiggling, the kinetic energy of anything's atoms.

温实际上是测任何物质里原子能。

The kinetic energy of all these satellites hitting the Earth would be like dropping nuclear bombs.

所有这些卫星撞击地球能就像投掷核弹一样。

So the change in kinetic energy of an object over time is just velocity times force.

那么 物体能随时间改变就是速乘以力。

If you watch a big car crash, the kinetic energy is breaking down throughout the whole move.

如果你看到一辆大型汽车相撞，能在整个过程中都在分解。

Ok, we know the kinetic energy of an object is half of its mass times its velocity squared.

那么 能随时间变化就是。

Temperature, is experienced by you and me as hot or cold but at the atomic level it's kinetic energy.

我们能感觉到温就只是" 热" 或" 冷" ，但在原子层面，温就是原子能。

When heat is added to a body, it speeds up the kinetic energy of its molecules.

当身体吸收了热，身体中分子能就会加快。

Meteoroids may usually be small, but they're screaming fast, and have a huge amount of kinetic energy.

流星体通常都很小，但是它们速非常快，并且有巨大能。

So there's an equation that describes the relationship Dianna's talking about: the equation for kinetic energy.

这里有一个等式，描述了戴安娜所说关系：能方程。

Above 4 degrees Celcius, the kinetic energy of the water molecules keeps their interactions with each other short.

4 摄氏以上时，水分子能使其间互时间很短。
