The rotation system has the difference for fixed-point rotation and circled-point rotation.
The style of force to control rotation on objects also differs between inner system tractor style and outer system control which includes single direction interception typeand the omni direction interception type.
When using different centripetal force to control different rotation system ,the vector direction of the centripetal force can behave differently between fixed-point charactors.
The vector direction of the fixed-point characrized centripental force doesn't have cut directioned flat translation whereas direction-fixed force does.
The conservation of the angular momentum only stands correctly in rotation system controlled by direction-fixed centripental force.
兄弟,我翻累死了,查收一下吧~
