2. But if you store the energy too early, it will
dissipate. (For example, if you stay low with bent knees for a second, you cannot move fast.
但如果你储存能量的时机太早,能量被浪费了(比如,如果你弯曲膝盖保持低位片刻,实际上你并不能快速移动。)
3. It's energy we
dissipate as heat primarily through the braking system, and therefore energy which, if we recover, is additional to the total energy.
当热量主要通过刹车系统时,能量与之一起消散,所以如果我们回收它们的话,这个能量就是额外的能量了。
