Quizplus · Accepted Answer

Ignoring air resistance, no internal forces or movements (such as rotating, stretching upwards, or sideways) can alter the motion of the center of mass of a system. According to the conservation of momentum, the center of mass of a system will continue to move in the same way unless acted upon by an external force.
