How does the centre of mass of an isolated system move?
Answers
the center of mass of a distribution of mass in space is the unique point where the weighted relative position of the distributed mass sums to zero, or the point where if a force is applied it moves in the direction of the force without rotating. on the other hand an isolated system consists either of the following: a physical system so far removed from other systems that it does not interact with them. a thermodynamic system enclosed by rigid immovable walls through which neither matter nor energy can pass.In an isolated system, there is neither energy exchange nor particle exchange. Therefore, the work done on/by the system is zero. In contrast, in a closed system, there is energy exchange but not particle exchange. ... We also have work done on the system equals "negative" work done on the surroundings
