The system is the object or the collection of objects that you are interested in (usually to describe its motion, explain why it follows some path, etc.). A system has various physical quantities associated with it: mass, energy, momentum, angular momentum, and entropy. These quantities can change for a system by interacting with the surroundings. | The system is the object or the collection of objects that you are interested in (usually to describe its motion, explain why it follows some path, etc.).
