Unformatted text preview: internal force on the ith particle. M A = Σ i F net i,ext + Σ i F net i,int . The last sum vanishes on using Newton’s third law, and we have M A = Σ i F net i,ext = F net,ext This last result may also be written F net,ext = d P /dt = M A = Md V /dt = Md 2 R /dt 2 , where P is the momentum of the system. This result is really the same as that for a single particle. In conclusion, the center of mass moves as a particle of mass M, position R , velocity V , momentum P , acceleration A , acted on by F net,ext . Examples[in class]...
