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

当它被释放时，它就变成了能。

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

温度实际上是测量任何物质里原子的能。

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

这个能取决于物体的质量和它移的速度。

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

能越大，越能产生更大质量的粒子。

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