词语势能拆分为汉字：
势字的拼音、笔画、偏旁部首、笔顺、繁体字，势字字源来历，势字演变
权力，威力：～力。权～。～利。～均力敌。表现出来的情况，样子：姿～。气～。山～。局～。虚张声～。守～。～必。～能。～不可挡。因～利导。……

1. 能 [néng]2. 能 [nài]能 [néng]才干，本事：～力。～耐。才～。有才干的：～人。～手。贤～。～工巧匠。～者为师。胜任，善于：～够。～柔～刚。力所～及。欲罢不～。～动。会（表示可能性）：小弟弟～走路了。应该：你不～这样……
汉语拼音：shì néng
When an infantry patrol sets up in the town square, its potential energy remains as a force to be reckoned with.
当一支步兵巡逻队出现在城镇的广场上时，其所具有的势能则将一直保持为一支需要认真对待的力量。This function of position that tells you how much actually energy stored somehow by the force field, and this gradient gives you the force.
这个关于位置的函数告诉我们，处于力场的某点有多少势能，梯度则告诉我们力。And the answer is yes, we can, because as long as the matter that swirls in is outside the event horizon, it would still be very hot.
因为只要物质，在视界外部，旋转，它还是会变得很热，因为重力势能。To evaluate the potential energy we first observe that every positive ion is in a position equivalent to that of every other position ion.
为计算势能，我们首先要注意到，每一正离子所处的位置与另一正离子所处的位置完全相当。You may say, gee, - that's sort of a strange thing-- negative potential energy.
你也许会说，上帝啊，这可真奇怪-，负的势能。Now, what we would like to do is we would like to convert all this gravitational potential energy into kinetic energy of that disk.
现在要做的，就是要转化，所有这些重力势能，变成圆盘的动能。The minus sign is telling you that the force is always pointing in the direction of the potential energy.
力一直是指向，这个方向的，它和势能的增长方向，这就是负号。It's as if the backswing is stretching something, building potential energy that wants to release and fly forward.
就好象后摆是在拉伸什么东西，积聚了势能，而想要释放出来向前飞行。The sum of the kinetic and potential energy of the body is called its total mechanical energy.
物体的动能和势能之和称为物体的总机械能。
