What is E=MC^2 mean?

Answer 1

The formulation of E=mc^2 was originally developped and published by Henri Poincare in 1900 . It related the definition of energy limit of a mass structure where the limiting velocity of the structural components mass is the speed of light referred above as "C", It basically means That a phenomenon of Energy "E" is required to form that particular value of mass. into a structure having a particular architecture. This idea promted Einstein to originate a mass structure formula which he interpreted as mass increase(formation) as a function of velocity. Others as Richard Carezqani have interpreted it in the reverse ;that is a moving mass decreases with velocity.
It is a matter of choice as this is interpreted.
Basically all formulations in Physics obey the 2nd law of thermodynamics which intinsically says that in order to obain something (a change of kinetic energy of a moving mass)a price must be paid. So the ideas that a mass at rest has maximal mass and when its moving it has less mass obeys this law and is the more realistic theory in physics,than saying a mass in motion increase as it motion velocity increases.

Answer 2

One person wrote "From the equation it is clear that mass can be converted into energy".

This is quite wrong. Mass cannot be converted into energy. Mass and energy are two different quantities. The mass of an object does turn out to be proportional to the energy content of an object though, with the factor of proportionality being "c squared".

There are processes where people who doe not understand Relativity think mass is being converted to energy, such as when an atom "splits". What really happens is that both energy and mass are conserved--they have to, because they are both proportional to eachother!-- with a decrease in total REST mass, but with the actual total mass not changing. (A moving object has more mass than that object at REST)

Answer 3

Though they don't look and feel the same, it means that mass and energy are equivalent to each other. Also, if you were to convert a gram, say, of mass to some form of energy, it would be a large amount of energy, because c^2 is pretty big. This energy isn't the same as the enthalpy of reaction (heat of reaction) from burning a lump of coal for instance, a normal combustion process. For in such processes the protons, neutrons and electrons in the reactants are present in the products after the chemicals react. The equivalence of mass and energy says that one can be completely converted to the other. It doesn't say how this is to be done, however.

Answer 4

That energy equal the mass times the speed of light squared.

E = energy
M = Mass
C = the speed of light
C^2 = C * C

Answer 5

E is energy
M is mass
C is the speed of light.

its the formula for converting or finding the energy for mass
or mass to energy

Answer 6

E=energy released
M=mass destroyed
C=velocity of light in vacuum
this formula was derived by Einstein and is known as Einstein's energy-mass eqation.
From the equation it is clear that mass can be converted into energy. Example is nuclear fusion.

Answer 7

energy equals mass times the speed of light squared.
