I was thinking about the equation
e = mc^2
and started to get seriously confused.
The confusion didn't come from this equation, but from the dimensionality of it, and then
the dimensionality of energy itself.
So a standard formula for energy for the most part.
e = kg (m/s)^2
e = kg * m^2 * s^-2
Breaking this up... we have a scalar... kg. We have an acceleration s^-2 curve. Then we have this Plane m^2 for distance. My initial reaction is shouldn't this be m^3 ?
This definition for energy (a very common one) seems to be missing a dimension. Energy is 3 dimensional right? An explosion of force or energy explodes in all directions, and not just on a plane.
Just so you follow me on this...
A one dimensional unit will be like (m).
A 2 dimensional unit, a plane, will be like (m^2)
A 3 dimensional unit, a sphere, will be like (m^3)
a volume for a sphere is 4/3 pi * r^3
volume for a cube is m^3
So I am confused. I have looked at other equations that do this same thing.
E = m c^2 ... E = M * (constant * constant) *(m^2)*(s^-2)
so Energy is flat?
I am confused. Help me out here.
