Apr 19	comment	How do forces work This seems like an interesting answer. If I understand the comment correctly it seems to say that force isn't quite the point. What's the point is the fact that acceleration occurs. Since acceleration implies an increase in energy in the accelerated entity, the question then becomes (at least in my mind) how does that energy transfer work/happen?
Apr 19	comment	How do forces work Interesting how in the video Feynman spent 7 1/2 minutes talking around the question and ended up saying that he couldn't explain it in intuitive terms.

Feb 13	comment	storing energy (as mass) It sounds to me that this answer and the one by @Manishearth are both saying that the additional mass is stored in the field/space itself. That seems like a strange concept, but that's why I asked the question. So to summarize, if one had an isolated system of masses, enclosed, say, in a rigid container, and modified it by separating the internal masses, then the system as a whole would have more mass than before. That could be measured, say, by applying a force to the container and checking its acceleration. The before and after results would be different. Right?

Feb 13	comment	What does activation energy actually do? Thanks. I guess that answers it.

Feb 12	comment	storing energy (as mass) I also asked the question on [ goo.gl/52V3t ] (Google+) and got a good answer in the comments. I can't post it here because I don't have authority to do so before 8 hours.

Feb 6	comment	Terminology question about energy Yes, that's it. Thanks.

Feb 6	comment	Terminology question about energy Also, I'm confused since potential energy is (or can be) used to do work as it moves from potential to waste heat. Is it really accurate to say that an entropy increase can be used to do work?
