What is the moment of inertia for rotation of a rod about this axis?

关于这个轴的,旋转动动量是多少？

youdao

For the moment of inertia, we want the square of a distance to the axis of rotation.

至于转动惯量，要求的其实是到旋转轴距离的平方。

1/2I So this can also be written as one-half I, C I put a C there you will see shortly why, because the moment of inertia depends upon which axis of rotation I choose times omega squared.

它也可以被写成，这里我写上,你们马上会发现原因，那就是转动惯量,取决于我选择，哪一个转动轴,乘以ω的平方。
