The energy or a rotating mass.........

A flywheel, after it is set in motion has a continuing motion all its own. We cannot forget this detail.

It has been my observation, to date.....  that a teter totter cannot continue a motion.  Exchanging positions of a mass are just that .....  exchanging of a position, which leads us to the active participation of a FREE FALLing mass.  Only a     FREE FALLing  mass can  

gain

the extra push that is necessary to continue a rotation.

a mass in Free fall        is required    An exchange of position, cannot give enough energy to continue the rise of one mass against the descending of another

To achieve the success that we all seek          a tireless effort must be given
