The Magic of Energy（能的魔力）
Mechanical Energy
机械能
11. In simplest terms, this is the energy of a moving object. Your heartbeat, the pushing of a lawn mower, a baseball speeding through the air, water falling onto a waterwheel, the prying up of a rock with a crowbar-all are mechanical energy, which, of course, was another form of energy earlier.
11、用最简单的术语来描述，机械能就是移动着的物体拥有的能量。你的心脏跳动、推进割草机、棒球在空中高速飞过、水落入水轮机、用撬杠撬开石头等等，所有这些都是机械能，当然，在转化之前它是另一种能量形式。
Electrical Energy
电能
12. Electrical energy usually has to be changed to another form before it actually does what we want it to do. In the toaster, it changes to heat; in a tiny wrist watch or a subway train or a 75,000 horse-power industrial motor, it changes to mechanical energy. In an industrial process called electrolysis, it changes to chemical energy.
12、通常情况下，电能必须先转化为另一种形式的能，才能为我们所用。对烤面包机来说，电能转化成热能，在一个小小的手表里或者地铁列车里或者一台75000马力的工业电动机里，电能转化成机械能。在所谓的电解工业的过程中，它转化成化学能。
Chemical Energy
化学能
13. Various fuels such as coal, gas, oil and food are common examples of chemical energy. These fuels give off heat when they burn. The process is called combustion or oxidation, and the heat itself is a form of energy. Man uses the energy from some kind of fuel for everything from flying to the moon to thinking about it.
13、最常见的化学能包括煤、天然气、石油、和食物等各种各样的燃料。当这些燃料燃烧时释放出热能。这个过程我们称之为燃烧或者氧化反应，同时热本身也是能量的一种形式。人们从不同燃料中得到的能量，并用这些能量做任何事情，大到飞上月球，小到头脑的思考。
14. A special kind of chemical energy is nuclear energy, sometimes called atomic energy. These names come from the fact that the source of energy the nucleus, or core, of the atom, nuclear fuels much as plutonium and uranium give off heat energy when fission(the splitting of atoms in these fuels) occurs. Already we have seen tremendous advances in the use of nuclear energy for peaceful purposes, and many people see nuclear energy as the future answer to almost all of our energy need.
14、核能是一种特殊的化学能，有时候我们称之为原子能。这个名称来自于原子能来源于核、或者原子核这样的事实。当核燃料，例如钚和铀，发生核裂变时释放出热能（这些燃料中原子发生分裂）。我们已经看到和平利用核能所带来的巨大好处，并且很多人认为核能可以看作解决未来人类能源需求问题的答案。
15. Energy-the kind of magic we can't live without.
15、能，是与人类生存息息相关的一种魔力。
