“The same law takes place in a system, consisting of many bodies, as in one single body, with regard to their persevering in their state of motion or of rest. For the progressive motion, whether of one single body or of a whole system of bodies, is always to be estimated from the motion of the center of gravity.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Newton's first law applies to both individual objects and composite systems, stating that motion or rest persists unless acted upon, and that a system's overall motion is determined by its center of mass.
In simple terms: Inertia governs single bodies and whole systems alike.
Key Takeaway
Center of mass dictates system motion.
