gravitational potential energy

Mhy You see? mgy is gravitational potential energy.

你们看，是重力势能。

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。

So the slowdown, the "braking" is now done because of a conversion from your linear speed which comes from gravitational potential energy to the rotation of the disk.

所以减速，刹车通过，能量的转换达到了，从，重力势能，转化到旋转圆盘上。

We call mgy* we give that a name," gravitational potential energy."

我们把mgy叫做。，给它一个名字，重力势能

In the transition region of accretion disk, the angular velocity deviates from and is smaller than the Keplerian angular veloeity if the wave dissipations are included, and the gravitational potential energy will convert into heat or kinetic energies of accretion gas.

吸积盘内缘区域的波阻将使盘内的角速度偏离开普勒速度而减小，引力势能使流体加热和加速。
