The equipartition theorem states that a particles' kinetic energy-the energy it possesses due to motion-is determined only by its temperature, not its size or mass.
能量均分定理是指粒子的动能——即粒子移动具有的能量——只由其温度决定，而非其大小或质量。

Whether you stay in your reference frame or in the reference frame of the center of mass, it's immediately obvious that all the kinetic energy is lost.
无论你在对照系中，还是在质量重心体系，很显然，所有的动能都被损耗了。

During such a collision, their kinetic energy is converted into other particles (since, as Einstein showed, energy and mass are but two sides of the same coin).
