→About Annihilation
===About Annihilation===
*'''Annihilation''' occurs when [[particle]]s of [[matter]] and [[antimatter]] interact at extremely close range.
*Follows the principle of [[mass-energy equivalence]] (E=mc²).
*During '''annihilation''' the total [[Rest Mass|rest mass]], as well as the [[Kinetic Energy|kinetic energy]], of the [[particle]]s is equal to the total [[energy]] of the two [[Gamma-ray|gamma ray]] [[photon]]s.
*In '''annihilation''' [[Conservation of Momentum|conservation of momentum]] is conserved due to the [[momentum]] of the [[Gamma-ray|gamma ray]] [[photon]]s travelling in opposite directions.
*For Results in the production of [[Gamma-ray|gamma rays]] or other [[Subatomic Particle|particles]]. However, for a-level physics , you only need to consider the special case of 2 [[Gamma-ray|gamma ray]] [[photon]]s being [[emit]]ted.
