Center of Mass and System Motion

The center of mass helps describe the motion of a system of particles. For a group with n particles, the equation of motion can be extended from a single particle to the whole system. Each particle has a net force on it that comes from both internal forces and external forces.

When the motion of ...

The equation of motion for a single particle can be extended to a system of particles. Consider a system with n numbers of particles.

The net force acting on an arbitrarily chosen particle is the sum of the net external and internal forces.

This equation of motion can be applied to any other particle from the system, and adding the...
