It is a formula, e, m and c can represent an infinite amount of numbers, and are meant to be substitued by the number, as you need to know at least 2 of them to figure out the entire formula.

The equation E equals mc2 relates energy and?

*E = mc^2 'E' is the Energy 'm' is the mass ( kg) 'c' is the speed of light in a vacuum ( 3.8 x 10^8 m/s) 'c^2' is the speed of light squared. Hence E = kgm^2/s^2 , which are named 'Joules'. It is the Einsteinian equation , that if a mass looses mass, then the difference in mass is the energy released. NB It is very similar to the Kinetic Energy (K.E.) equation, which is K.E. = 0.5massvelocity^2.


Why doesn't the mass change in physical and chemical changes?

Under normal circumstances it is impossible to make atoms split apart, ie so that mass cannot be lost. This is a scientific law. In a Nuclear reaction mass can be converted into energy, e=mc2. This means that mass will be lost.


Where does the energy from the fusion reaction come from?

It arises from the internal energy of the nucleus, called the binding energy. In the case of light elements, joining two light nuclei to make a heavier one releases energy, because the binding energy changes. In the case of the heavy elements like uranium, splitting the nucleus into two smaller parts also releases energy, for the same reason. In both cases the end result loses a proportion of the initial mass of the nuclei concerned, and this loss of mass equates to the energy released via Einstein's equation E = mc2.


Non - matter examples?

Non-matter examples include light, sound, energy, and magnetic fields. These entities do not have mass or take up physical space like traditional matter, yet they play essential roles in the universe.

What does the letters mean for e equals Mc2?

it means e = MC2 which is M x c x 2


What is Mc2?

E means energy content m means mass c means spead of light so e = mc2 mean energy content equals mass into speed of light squared


What does pie equals MC2 mean?

Well, mc2 means matter and speed of light squared and pi is 3.141592654. I dont no what you mean by 'what does pi=mc2 mean' but i can work out the equation. Matter=0.111 Speed of light=299792458 m/s mc2=0.111times299792458=29979.24580000 29979.24580000squared=898755154.753421 898755154.753421 If you divide 898755154.753421 bi 3.141592654 it equals=1. This means an unknown number-pi

Where or when has e equals mc2 been or is used?

E = mc2 This is Albert Einstein's famous Relativity equation: Which means that in a vacuum the Energy is equal to the Mass times the Speed of light squared.


Where did albert Einstein create the formula 3 equals mc2?

The formula is E=mc2.


Relativity theory equals e equals mc2?

Yes. It is Einstein's celebrated equation, E=mc2. It means "energy equals mass times the speed of light squared." It tells how to convert mass into energy. Einstein showed through this that mass and energy can be changed into each other.


Was there any problems with e equals mc2?
