The amount of angular momentum, say, a spinning skater has depends on both the speed of rotation, and the weight and distribution of mass around the center.
角动量的大小,取决于旋转中的滑冰选手的旋转速度、体重和绕旋转中心的质量分布。
The curl actually measures twice the angular speed of a rotation part of a motion at any given point.
旋度实际上衡量的是,在任意给定点,运动旋转角速度的两倍。
So, for two skaters of the same mass rotating at the same speed, the one with its mass more extended in space will have the greater angular momentum.
因此,对于以相同速度旋转的两个同质量选手来说,肢体在空间中更为外扩的那个选手将具备更大的角动量。
