A TeV is a teraelectronvolt, i.e., it is 10¹² electronvolts, or 1,000,000,000,000 eV. An electronvolt is the amount of energy gained or lost by an electron when it is accelerated by the electrical potential of one volt, or 160.22 nanojoules (nJ). An electronvolt (symbol eV, or, rarely and incorrectly, ev) is the amount of kinetic energy gained by a single unbound electron when it passes through an electrostatic potential difference of one volt, in vacuum. ... To help compare different orders of magnitude this page lists energies between 10−7 joules and 10−6 joules (0. ... Properties The electron is a lightweight fundamental subatomic particle that carries a negative electric charge. ... Electrical potential is the potential energy per unit charge associated with a static (time-invariant) electric field, also called the electrostatic potential or the electric potential, typically measured in volts. ... The volt (symbol: V) is the SI derived unit of electric potential difference. ... The joule (symbol: J) is the SI unit of energy, or work with base units of kg·m2/s2. ...

It requires 13.6 eV to remove the electron in a hydrogen atom to infinity. General Name, Symbol, Number hydrogen, H, 1 Chemical series nonmetals Group, Period, Block 1, 1, s Appearance colorless Atomic mass 1. ...

The eV, and its multiples, keV, MeV, GeV, TeV are used in particle physics as their magnitude is more relevant to the scale of subatomic particles. keV is an abbreviation of kiloelectronVolt ... An electronvolt (symbol: eV) is the amount of energy gained by a single unbound electron when it falls through an electrostatic potential difference of one volt. ... A GEV (or Ground Effect Vehicle) is vehicle that takes advantage of the aerodynamic principle of ground effect (or Wing-in-ground). ... Particles erupt from the collision point of two relativistic (100 GeV per nucleon) gold ions in the STAR detector of the Relativistic Heavy Ion Collider. ... A subatomic particle is a particle smaller than an atom: it may be elementary or composite. ...

As explained by Einstein, the eV can be used interchangeably as a unit of energy and mass, and often particles are described as having a mass in eV; for example, an electron has a mass of 0.511 MeV and a proton around 930 MeV. Albert Einsteins equation E=mc² is among the best-known equations of all time. ... Albert Einstein, photographed by Oren J. Turner in 1947. ... Mass is a property of a physical object that quantifies the amount of matter it contains. ... Properties In physics, the proton (Greek proton = first) is a subatomic particle with an electric charge of one positive fundamental unit (1. ...

High-energy particle accelerators use TeV. A 1960s single stage 2MeV linear Van de Graaff accelerator, here opened for maintenance A particle accelerator is a device that uses electric and/or magnetic fields to propel electrically charged particles to high speeds. ...

This is also slang for whatever. As in the response whatever. Like:

"You wanna go to the movies?" "'Tev. Sounds cool. Whaddya wanna see?"
