"Squared" means you take the number it's attached to ... including the unit ... and
multiply the whole thing by itself. For example, when you take inches of length and
square it, you get inches squared of area.
(Miles per hour) squared doesn't have any obvious physical significance, but when you
multiply that by mass, and massage the result just a little, you have familiar, everyday
units of energy.
C = speed of light
Energy = mass x speed of light(squared)
Energy=Mass xC2 What does the C stand for?
E=mc squared
Einstein developed the E = mc squared formula.
c in E=mc squared meaqns the speed of light
mass * (Speed of light)^2
E=MC squared was Einstein's formula for splitting the atom. Energy = mass X speed of light squared
2 mc squared
C = speed of light
Energy = mass x speed of light(squared)
Energy=Mass xC2 What does the C stand for?
E=mc squared
mc does not stand for anything.
Einstein developed the E = mc squared formula.
mc squared
The m is for mass and c is for the speed of light. The attached link is Albert Einstein explaining the theory of relativity. It has subtitles as his accent is very thick.
