Electronvolt (unit: eV). Electronvolts are a traditional unit of energy, particularly inatomic and nuclear physics. An electronvolt is equal to the energy gained by a single electron whenacceleratedthrough1 voltofelectric potentialdifference. The work done on the charge is given by the ...
In physics, energy is defined as the ability to do work. The physical notion of energy encompasses mechanical (potential and kinetic) energy, radiant energy, chemical energy, heat, electric energy, and nuclear energy. Biophysical structures of society are intrinsically linked with the biosphere ...
