According to Einstein's theory of special relativity, a body at rest possesses a tremendous amount of energy, even without any motion. This intrinsic energy, known as rest energy, is directly related to its mass through the iconic equation $E=mc^2$. Understanding what is the energy of a body at rest requires looking beyond simple kinetic energy to explore the fundamental nature of mass and energy.
