TeV (Tera-electronvolt)

A Tera-electronvolt (TeV) is a unit of energy commonly used in particle physics. One TeV equals one trillion electronvolts, which are the energy units for subatomic particles. To put this in perspective, it represents the energy gained by an electron when it is accelerated through a potential difference of one trillion volts. TeV is used to describe the energies achieved in powerful particle accelerators, such as the Large Hadron Collider, to explore fundamental questions about the universe and the particles that compose it, including the search for new particles and understanding forces at the smallest scales.
