==Key Stage 4==
===Meaning===
'''Mass-Energy''' is the observation that [[energy]] and [[mass]] together form a conserved quantity in a [[Nuclear Reaction|nuclear reaction]] or [[Radioactive Decay|decay]].
===About Mass-Energy Equivalence===
: [[Energy]] and [[mass]] are related by [[Einstein]]'s famous equation <math>E=mc^2</math>.
: [[Energy]] can become [[mass]] and [[mass]] can become [[energy]].
: [[Energy]] becomes [[mass]] in a [[Particle Accelerator|particle accelerator]] which gives [[particle]]s so much [[Kinetic Energy Store|kinetic energy]] before they [[collide]] that during the [[collision]] that [[energy]] becomes [[mass]] and creates new [[particle]]s.
: [[Mass]] becomes [[energy]] in [[Nuclear Reaction|nuclear reactions]] and [[Radioactive Decay|nuclear decays]].
: When a [[Nuclear Reaction|nuclear reaction]] takes place the [[mass]] of the products is less than the [[mass]] of the reactants as some of the [[mass]] has been converted into [[energy]] and [[Energy Transfer|transferred]] away by [[gamma-ray]]s.
