Analyzing E=MC2: What Does Energy Have to Do with Distance?

[Makep]

By analyzing E=MC2 dimensionally, we will get these results.

kgM/S2 = kg(M2/S2)
= kg(m)(m/s2)
= kgm/s2(m)
= E x distance

E != Es where E = energy and s = distance or displacement. What we are seeing here with Einstein's relativity is that energy has a factor of distance or space as well. Is this wrong or can soeone correct me on this, please?

Es is no longer energy but something else and should be treated as such, I believe.

kg\frac { m} {s^2} = Mass x acceleration is the units of Force, not energy. Energy is kg\frac { m^2} {s^2} just like in E = m c^2

Thanks for the correction.

Of course, mc² has the same units as (1/2)mv², the kinetic energy.
