Has anyone ever noticed that, even in classical physics, energy is shown as a scalar multiple of mass?(adsbygoogle = window.adsbygoogle || []).push({});

For example, consider the joule;

1 J = 1 kg*(m/s)^2

If you consider the units of motion (m/s) to be a vector quantity, then squaring such a vector would be interpreted as a dot product that produces a scalar.

1 J (energy) = [mass in kg]*[scalar speed]

Which is eerily similar to E=MC^2. Thus, whether anyone in the past realized it or not, did they inadvertently stumble on the mass-energy equivalence just by dealing with these units?
