Now I'm going to rotate this about this axis-- - it's going around like this-- with an angular velocity omega R and this is at a distance, R.

然后我将使其绕轴旋转-,像这样旋转-,为角速度,这个距离记为。

Your velocity is in this direction R and there is a certain distance to the center, R.

是这个方向的,离中心的距离为。

youdao

R And the track has a radius R, and at this moment in time the angle equals theta, and here is the object.

轨道半径是，在这个时刻,角度等于θ,这是物体。

In an orbital is remember that this area right here at r equals zerio, that is not a node.

例如对于１ｓ轨道,记住这里ｒ等于０处不是一个节点。

And we can simplify this expression as saying negative e squared over 4 pi, epsilon nought r squared. Epsilon nought is a constant, it's something you might see in physics as well.

也会遇到它,在这里，你可以就把它,理解为一个转换系数,我们需要做的。
