Document Summary

Recall that the amount of angular momentum is related to the radius of gyration squared, as in. Just a subtle motion of the mass will have a large effect because it is squared. By changing radius of gyration you have a significant effect on your rate of rotation. So when you change the radius of gyration, you change the angular velocity squared. From tight tuck with small radius of gyration to layout arms overhead with large radius of gyration. By taking off as laid out as possible you store up as much angular momentum as you can. Since individual segments can generate angular momentum internally, this can. Since individual segments can generate angular momentum internally, this can be used to delay or speed up rotation in the rest of the body. If you create angular momentum in your arms the body needs to create angular momentum against that to maintain neutral.
