Body
Body is any mass, especially one considered as a whole.
Mass
Origin: “barley cake.” Mass is the quantity of matter as determined from its weight or from Newton’s second law of motion.
System
Origin: “that stands together.” In physics, system refers to a physical structure considered as a whole.
