Can I put in my 2₵ worth? The way I understand Biker (of course it's for him to say) is the following: how did physicists arrive the conclusion that energy is always conserved? If I am right here, most of the answers address a very different question, namely: How can it be proven that energy...

First of all, I want to thank all who commented on my question. Based on these answers I am satisfied that, indeed, Newton's laws imply that mass is "additive"; no additional postulate is needed. Furthermore, I learned that it would be a good idea for me to study Hamiltonians and Noether's...

Within the context of Newton's laws, it seems implicitly understood that mass is an additive property of objects. My question is: should this be considered "just" an experimentally confirmed fact, or is is provable from Newton's laws? The following is a more precise context for this question...
