MassEnergieRelation
MassEnergieRelation is the physical principle that mass and energy are interchangeable and intimately linked. In the framework of special relativity, the rest energy of a particle is E0 = m c^2, and the total energy is E = γ m c^2, where γ is the Lorentz factor. The broader relation implies that all forms of energy contribute to gravitational and inertial effects, and that mass can be converted to energy and vice versa.
Historically, the concept arose from Albert Einstein’s 1905 work on special relativity and has since become
Mathematically, the mass–energy relation is often expressed as E^2 = (p c)^2 + (m c^2)^2, where p is
Applications of MassEnergieRelation span nuclear energy, particle accelerators, astrophysical processes, and medical imaging (for example, PET
In contemporary usage, the term is often treated as a descriptive label for the mass–energy equivalence principle
