The energy of motion is called kinetic energy.

运动的能量叫做动能。

This extra energy comes from the planet's own energy of motion around the sun.

额外的能量来自于行星绕太阳旋转时自身的动能。

Eventually they merge, their huge energies of motion absorbed by the orbiting stars, puffing them up into vast, sweeping orbits.

最终，它们会合并在一起，它们巨大的运动能量被轨道上的恒星吸收，将它们膨胀到巨大的、广阔的轨道上。

Kinetic energy is the energy of motion, and as the ball moves, there are two points

动能是过程中发生的能量 运动，当球在运动时，有两个点。

At the most basic level, temperature is a measure of how much kinetic energy -- that is, the energy of motion -- is in a system.

在基本层面上，热量是能量的量度 动能，意味着动能存在于每个系统中。
