Actual Formula for E=mc2?

Question

Just wondering if anyone knew the actual long hand version of this well known formula made famous by Einstein?

I meant "invent" when I said that about Einstein making it famous, I was just being funny. Of COURSE he discovered it (God invented it but that's a whole other story).

And I mean the loooong mathmatical version. (Not the Energy equals mass times the speed of light squared) I hear it's REALLY long!!!

Answer 1

The formula expanded a bit is: E (joules or kg*m²/s²) = m (kilograms) multiplied by (299,792,458 m/s)2

E is Energy, m is mass and c is the speed of light in a vacuum.

Off the subject, but an important reply to Fresh Prince and those of the same mind:

You seem pretty mad. It is unfortunate that "[we] people disgust [you]." It does not diminish Einstein’s discovery to say God created the highly balanced universe which is made up of this mathematic formula as well as all formulas - discovered and undiscovered. Einstein was doing wonderful work in unlocking the mysteries of Creation - he was a genius among geniuses

Einstein himself believed in a "god / creator" - not the God of the Bible, but a Creator nonetheless. He was not closed - he acknowledged that the universe is so finely balanced on finite mathematical principals, there is a higher intelligence governing things that we cannot comprehend. He spent his life exploring the wonder of what has been created and set before mankind. Please cast aside your disgust. No one is taking credit away from Einstein - or you.

Regarding religion, Einstein said: "The most beautiful and deepest experience a man can have is the sense of the mysterious. It is the underlying principle of religion as well as all serious endeavor in art and science. He who never had this experience seems to me, if not dead, then at least blind. To sense that behind anything that can be experienced there is something that our mind cannot grasp and whose beauty and sublimity reaches us only indirectly and as a feeble reflection, this is religiousness. In this sense I am religious. To me it suffices to wonder at these secrets and to attempt humbly to grasp with my mind a mere image of the lofty structure of all that is there."

When asked: "[Do] You accept the historical Jesus?"

He replied: "Unquestionably! No one can read the Gospels without feeling the actual presence of Jesus. His personality pulsates in every word. No myth is filled with such life."

No, Einstein did not believe in God as Christians believe. But he recognized the order of the universe as a signpost to a higher being. The point is, there is no cause to be "disgusted" by ideas outside your paradigm. I am not disgusted with you.

Take a hint from Einstein - the consummate scientist who believed in a Creator: "...science without religion is lame, religion without science is blind." I will not be blind, so please do not be the former. Take a look from another perspective; you may learn something of value.

Remember, you may be angry with God, deny God, ignore God, and not care to inquire with an open mind, but God loves you anyway.

Have a blessed day, my friend (that is a positive statement, please take it as such).

Answer 2

Energy equals mass times the speed of light squared. He did not "make it famous," he discovered it.

Answer 3

E=M*C2 is a mass energy equivalence .it tells us that even if body isnot moving it has energy in it..it also shows that mass and energy can be converted into one another by suitable conditions. This formula also gives the amount of mass lost from a body when energy is removed. In a chemical or nuclear reaction, when heat and light are removed, the mass is decreased. So the E in the formula is the energy released or removed, corresponding to a mass m which is lost. In those cases, the energy released and removed is equal in quantity to the mass lost, times c2. Similarly, when energy of any kind is added to a resting body, the increase in the mass is equal to the energy added, divided by c2.

Answer 4

Energy = Mass * (Speed of Light squared)

This gives the energy that would be produced if a certain amount of mass were converted entirely to energy.

Answer 5

E = (mc^2)/sqrt(1-(v/c)^2)

Where

m is the invariant mass or rest mass

v is the velocity of the mass m as measured in the observer's inertial frame, and

c is the speed of light in vacuum

This equation is derived from:

E^2 = (K.E.)^2 + (P.E.)^2

A particle of mass, m, moving with velocity, v, in free space is:

E^2 = (pc)^2 + (mc^2)^2 = (p^2+m^2c^2)c^2

where p is the relativistic momentum of the particle

since p^2 = m^2v^2/(1-(v/c)^2) (this comes from Lorentz transformation of position x and time t, thus velocity is adjusted with an extra factor sqrt(1-(v/c)^2))

E^2 = (mc)^2 (v^2+c^2(1-(v/c)^2)/(1-(v/c)^2)

= (mc)^2 (v^2+c^-v^2)/(1-(v/c)^2)

= (m^2c^4)/(1-(v/c)^2)

Hence, E = mc^2/sqrt(1-(v/c)^2)

Answer 6

i dont claim to understand it, but here goes

energy= mass times the speed of light squared

Answer 7

E = m(final)c^2

where;

m(final) = m(init) / sqrt(1 - (v^2/c^2))

so,
mass approaches infinity as the velocity approaches speed of light,
then,
E approaches infinity as mass approaches infinity

Answer 8

Yeah, sure, "god" invented it.......you people disgust me, whenever science makes a discovery, you immediately say "of course, god must've made it" even though there's no mention of it in religion.

Answer 9

Check out http://en.wikipedia.org/wiki/E%3Dmc%5E2 for the full formula and some good links for more in-depth information

Answer 10

That is it solve for different items. E=mc2
m=e/c2 .
