The energy-momentum relation describes the relationship between energy, momentum, and mass for a particle, encapsulating the principles of special relativity. It is expressed by the equation $$E^2 = (pc)^2 + (m_0 c^2)^2$$, where $E$ is the total energy, $p$ is the momentum, $m_0$ is the rest mass, and $c$ is the speed of light. This relationship emphasizes that energy and momentum are interrelated properties of particles, regardless of their state of motion.
