The energy of motion is called kinetic energy.

运动的能量叫做动能。

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量度。

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量还有动能和势能。

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

之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.

由于轮胎对挤压力产生反弹，动能传化为热量产生动能浪费。

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

动能越大，越能产生更大质量的粒子。

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量和它移动的速度。
