What if the electron and/or positron initially had kinetic energy? This kinetic energy, combined with the rest mass energy equivalence, will provide the total energy released due to the annihilation. #annihilation #physics #alevelphysics #revision #physicsrevision | vt.physics

When a particle meets its equivalent antiparticle they both get destroyed, and their mass is converted into energy in the form of two gamma ray photons. Electron-positron annihilation is when a positron collides with an electron, resulting in the annihilation of both particles. Electrons (or β- particles) and positrons (or β particles) have equal mass but opposite charge. According to the physics of conservation of energy, their masses are converted to two gamma photons with an energy of around
