rotation moment of inertia的意思|示意

In rotation, force becomes torque, mass becomes moment of inertia, and acceleration becomes angular acceleration.

在旋转时，力变成力矩，质量变成转动惯量，加速度变成角加速度。

So we now have a way of calculating the kinetic energy of rotation provided that we know how to calculate the moment of inertia.

现在我们有一个计算，旋转动能的方法，如果我们知道，怎样计算转动惯量。

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？

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。

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。

Moment of inertia: turning around its axis of symmetry, object has the character keeping speed and the direction of the axis of rotation not changing.

转动惯性：物体在绕着自己的对称轴转动时，具有保持转速和转动轴方向不变的性质。
