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.
