This principle can be obtained from the current density associated with an electric field using the Poynting theorem. A system with time translation symmetry also exhibits it according to Noether's theorem. Special relativity expanded this principle to account for mass increases that occur at relativistic speeds.

This principle can be obtained from the current density associated with an electric field using the Poynting theorem. A system with time translation symmetry also exhibits it according to Noether's theorem. Special relativity expanded this principle to account for mass increases that occur at relativistic speeds. When it encompasses thermal, potential, and kinetic contributions, it is expressed in the first law of thermodynamics. For 10 points, name this principle of physics, which states that the total energy of a closed system will remain constant.
