Answer #1

Conservation of energy is one of the most important laws in physics. Not only does energy have many important forms, but each form can be converted to any other. We know that classically the total amount of energy in a system remains constant. Relativistically, energy is still conserved, provided its definition is altered to include the possibility of mass changing to energy.

If the formula for kinetic energy is KE=1/2mv^2 then why is Einstein’s equation for the total energy in a given mass E=mc^2? Shouldn’t it be E=1/2mc^2? They are kind of the same equation and in my mind Einstein was basically declaring that the energy a given mass would be limited by the maximum velocity observed in the universe.
