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。
Hence, the loss of gravitational potential energy of the block equals the gain of elastic potential energy of the spring.
因此，该物块的重力势能的减少，等于该弹簧的弹性势能的增加。
Then this will have a positive gravitational potential energy, and this will have one that is higher than this one by this amount.
那么它将是,正的重力势能，这样的话这点,就比另一点高。
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。
There is a conversion from gravitational potential energy to kinetic energy back to gravitational potential energy, and it will come to a stop here.
这就是重力势能，转换到，动能，再回到，重力势能，最终停在这里。
Okay, my goal was to evaluate for you the gravitational potential energy the way that it is defined in general, not in a special case when we are near the Earth.
好了，我的目标是，用通常的方式，为你们评价重力势能，不是用一个特殊的，接近地球的案例。
Rain energy and gravitational potential energy were original energies of rocky desertification form in nature ecosystem, and were direct or primary motivity.
石漠化形成的主要原动力是自然生态系统的雨水动能和重力势能，亦是其形成的直接动力或第一性动力。
The formal definition is that the gravitational potential energy at a point P is the work that I, Walter Lewin, have to do to bring that mass from infinity to that point P.
形式定义就是,它在点P的重力势能,等于我，将物体从无穷远处,移动至点P所做的功。
Working principles Airflow screen machine abandon gravitational potential energy principle of operation, using air as the carrier, kinetic energy of the operation principle of work.
气流筛分机摈弃重力势能作业原理，采用空气作载体，动能作功的作业原理。
If the compressibility of seawater is considered, the APE should be divided into two parts: The Available Gravitational Potential Energy (AGPE) and The Available Internal Energy (AIE).
考虑海水的可压缩性时，有效位能包括有效重力位能与有效内能两部分。
