GeV (Giga-electronvolt)

A GeV (giga-electronvolt) is a unit of energy commonly used in particle physics. It measures the energy of subatomic particles like protons or electrons. One GeV equals one billion (1,000,000,000) electronvolts. To give perspective, the energy produced when a single proton accelerates to this level is immense at the atomic scale—comparable to the kinetic energy of a moving mosquito. GeV helps physicists quantify and compare the energies involved in high-energy particle interactions, such as those studied in particle accelerators like the Large Hadron Collider, advancing our understanding of the universe's fundamental particles and forces.
