Document Summary
Definition: the center of mass of a system of particles is the point that moves as though (1) all of the system"s mass were concentrated there and (2) all external forces were applied there. Systems of particles: two particles. (m is the total mass, many particles, three dimensions. If the particles are distributed in three dimensions, the center of mass must be identified by three coordinates. They can now be replaced by a single vector equation: Newton"s second law for a system of particles. This equation is newton"s second law for the motion of the center of. Remarks: mass of a system of particles. is the net force of all external forces that act on the system. Forces on one part of the system from another part of the system (internal forces) are not included: m is the total mass of the system.
