GeV (Giga-electron Volt)

A GeV, or Giga-electron Volt, is a unit of energy commonly used in particle physics to measure the energy of subatomic particles. It quantifies how much energy a particle has or can transfer. One GeV equals one billion electron volts, where an electron volt is the energy gained by an electron when it moves through an electric potential difference of one volt. In practical terms, GeV helps scientists describe extremely tiny particles and their high-energy interactions, providing a scale to understand their behavior in particle accelerators and cosmic phenomena.
