OK first let me explain, I have NO formal physics background, not even high school, so please don't flame me if these are dumb questions(adsbygoogle = window.adsbygoogle || []).push({});

1. What unit of measure is E? If it were distance we could say miles or kilometers.

2. I understand that this formula is for mass at rest. If the mass were moving at 50% light speed, would the answer to E=MC^2 be half of what it would be for the same mass at rest?

3. In nuclear fusion I understand the energy is based on applying this formula to the mass left over when 2 atoms fuse. So looking at a Hydrogen atom, if .00794 atomic mass were converted into energy during the fusion, does that mean the energy gained from this fusion is Energy = .00794 x c^2? I don't know if that is the right number but I needed to apply one for the purpose of this question.

Thanks
