The energy of motion is called kinetic energy.

运动的能叫做动能。

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

当它被释放时，它就变成了动能。

Temperature is a measure of those atoms' kinetic energy.

温度是那些原子动能的度。

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

更快的运动速度导致了粒子的动能增大。

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

是个物理学家的玩具可以演示角动还有动能和势能。

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机械能。

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

由于轮胎对挤压力产生反弹，动能传化产生动能浪费。

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

动能越大，越能产生更大质的粒子。

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

这个动能取决于物体的质和它移动的速度。

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

温度实际上是测任何物质里原子的动能。

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的动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 物体动能随时间的改变就是速度乘以力。

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，动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 动能随时间的变化就是。

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

我们能感觉到的温度就只是" " 或" 冷" ，但在原子层面，温度就是原子的动能。

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

当身体吸收了，身体中的分子动能就会加快。

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，但是它们的速度非常快，并且有巨大的动能。

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，描述了戴安娜所说的关系：动能方程。

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

4 摄氏度以上时，水分子的动能使其间的互动时间很短。
