I know E - energy M= mass C= speed of light
but what does the 2 stand for ?
(in easy terms please )

you people are just saying squared as an answer ..
The proper way to answer is to say ..
energy equals mass times the speed of light times the speed of light that is how they are figuring out and that is done by squaring it off.
soo when figurung it all out ..
The little two means squared.
And, you probably do, but just incase, squared times by itself, for ecample, 2²=4 because 2x2 is 4.
so
Eis equal to (M)x(C²)

The two should be superscript since it means that the speed of light is squared in this classic Einstein equation. Since the speed of light is a very large number, and makes an even larger number when it is squared, this shows that a very small amount of matter can be converted into a very large quantity of energy. This is why that, although only a small quantity of the active mass in a nuclear bomb is converted into energy (less than 2% if I recall), it can release such huge quantities of energy to create such a large explosion.

It stands for squared, meaning the speed of light times itself is the conversion factor that is needed to convert mass units to energy units and vice versa.

It is read , Energy is equal to the mass times the constant [speed of light] squared.

In physics, E = mc² is the equation that expresses an equivalence between energy (E) and mass (m), in direct proportion to the square of the speed of light in a vacuum (c²)

2=Squared. So speed of light times the speed of light.

the speed of light squared
to the second power
it doesnt stand for anything
