| Abstract: | This paper expounds that if the instantaneous velocity center of a rigid body in the plane motion are taken as moment center, by applying the theo- rem of moment of angular momentum, then the velocity of moment center should be the instantaneous velocity of the center (not equal to zero) along the fixed trace of instantaneous center. Herein all the concerning formlae have been derived direct, and the fundamental concept is thus clarified. |
