    energy equals mass times the velocity of light squared

    The E represents energy.  The M represents mass.  The C represents speed of light.  What you have missing is that it's supposed to have "squared" after the MC.

    So what it means (in my non-physicist's terms) is that Energy equals MC when you multiply that by itself.

    In a over simplified manner, E=MC^2 is just describing how much energy is in a certain mass.

    To put this in perspecitve:

    The velocity of light is 3x10^8 meters/second.

    So 1 kg of material has (1kg)(3x10^8)^2=9X10^16 Joules............That is 9 with 16 zeros behind it.

    This is theory and we do not convert mass into energy at the same ideal situation that this describes but there is a lot of energy contained in mass.
