The correct expression for the kinetic energy of a particle in relativistic mechanics is given by $mc^2 - m_0c^2$, where $m$ is the relativistic mass, $m_0$ is the rest mass, and $c$ is the speed of light. This formula represents the total energy minus the rest energy, which is the definition of kinetic energy in the relativistic context.
