例句

• 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。

• So if I make a plot of the gravitational potential energy as a function of y, then I would get a straight line.

  因此如果我画一张，重力势能，受y变化的图，那么会得到一条直线。

• 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。

• When a torque is applied to a body, potential energy is imparted to the body, which accepts it in the form of kinetic energy.

  当物体上作用一力矩时，把位能给予了这个物体，物体以动能的形式接受这位能。

• 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。

• The explosive potential( energy content per unit mass) of hydrogen is about twice that of the methane in natural gas .

  氢的爆炸潜能（单位质量含有的能量）大约是天然气中甲烷的两倍。
