Rest energy in classical mechanics

[DrStupid]

You will find the relation E=mc^2.

Yes, but what does that contribute to the topic? In relativity we know that E is the total energy inside the container. How do you prove that in classical mechanics?

In relativity we know that E is the total energy inside the container. How do you prove that in classical mechanics?

We now know E=mc^2 as a fact that classical mechanics or saying more accurately classical non relativistic mechanics does not anticipate, need and prove. I prefer the fact to a theory.　Don't put new wine into old bottles.

I already wrote above that internal energy cannot be determinied in classical mechanics. That includes that classical mechanics doesn’t anticipate, need and prove E=mc². So I still do not see a new argument. Do I miss something?

Now you know that non relativistic mechanics failed. I do not think you miss anything.

Now you know that non relativistic mechanics failed.

I was well aware of it from the beginning (I even mentioned it in #18). You are quite off-topic if that was all you are trying to tell me.
