What is the motion relative to the centre of mass?

Motion of centre of mass has various applications in the real world. It is used for designing stable structures and vehicles, where low centre of mass make them more stable and faster. Even the motion of centre of mass applies to sportspeople, where athletes manipulate their centre of mass to optimi

The centre of mass moves as if all mass of the object is concentrated at one point while all external forces act on it. The motion of the centre of mass follows Newton's Second Law of Motion. That means that you can multiply the total mass of the system with the acceleration, which equals the net to
