The discussion centers on the relativistic energy equations for particles, specifically addressing the equations E = γmc² and E = √(p²c² + m²c⁴). It is established that while both equations are valid for particles with mass (m ≠ 0), the first equation fails for massless particles like photons, as the Lorentz factor γ is undefined when velocity (v) equals the speed of light (c). The equivalence of the two equations for massive particles can be demonstrated using the momentum formula p = mvγ.
