If you reversed E=mc(squared) say m=E/c(squared), is that a formula for fusion?

Question

So if energy was slowed by the rate o the speed of light squared, per energy quantity..it would turn into mass or a solid?

Answer 1

Well, regardless of what some are telling you...

switching E=mc^2 into m=E/c^2 is perfectly fine. They are both perfectly true statements and there is nothing wrong with either of them. And that fact is 8th or 9th grade algebra. You may form your own opinion on how far the two respondents who told you otherwise got in their math classes.

But your interpretation is wrong. In E=mc^2, the equation is telling you how much energy E is stored in a mass m. It means if you convert all the mass in m into pure energy, you'd get E out of it because mass is just another form of energy. Now if you switch the equation around, the meaning of the quantities don't change. So m=E/c^2 says that if E amount of energy all gets converted to the form of mass, you would get a mass of m out of it. The speed of light squared is just the conversion factor. Those are equivalent statements both physically and mathematically.

Answer 2

The equation describes the relationship between mass and energy. The relationship holds for fusion, fission, and any other phenomenon. The equation is not "the equation for fission" and any rearranging of it will not give you "the equation for fusion".

In both fission and fusion, small amounts of mass are converted to energy. In both processes the end products weigh slighly less than the starting materials.

Nature, in all likelihood, found a way to turn energy into mass at the big bang. NOBODY understands exactly how this transpired, yet, and you've got a long way to go before you're ready to tackle that problem. Don't bite off more than you can chew. ;)

Answer 3

Interesting question, but technically you are wrong.

E=mc^2 is the same equation as m=E/c^2. This equation describes the change in mass corresponding to a change of energy, or the change of energy corresponding to a change in mass. One use of the equation is to calculate the energy released in a fusion reaction.

But in you explanation your are not talking about fusion. Instead you are talking about pair production. If you have a high enough energy photon pass near an atom there is a chance that that photon can transform into an electron and positron. And E=mc^2 is used to find the required energy of the photon to produce the e- p+ pair.

Answer 4

that isnt really what that equation is saying. The equation is used mostly when finding mass defects. In fusion, a certain mass of reactants is consumed and a mass of product is formed. The product mass is lower than the mass of the reactants. This difference in mass is call the mass defect and the energy released in the reaction can be found by inserting the mass defect into einstein's equation. It really doesnt have anything to do with slowing down energy or speeding up mass

Answer 5

Saying "E=mc(squared)" reversed is "m=E/c(squared)" shows a basic lack of understanding of second grade math.

You need to read a book!

Answer 6

Dude, you can't just randomly switch things around in an equation an expect it still to be true. m!=E/c^2. m=c^2/E.

But if you figure out a way to slow down energy, give me a call. I work with kindergarteners.
