回答: isn't that a question of high school physics? 由 steven 于 2005-5-04, 17:46:27:

重心引力 -- micro gravity in space. The micro gravity must be equal to the centripetal (or centrifugal) force, is this right?

• centrifugal force is the reaction of centripetal force. - steven (22 bytes) 2005-5-04, 17:54:44
  • Don't agree. My impression is that centrifugal force - cornbug (44 bytes) 2005-5-04, 17:58:17
