==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.

 : [[Proton]]s and [[neutron]]s bound in the [[Atomic Nucleus|nucleus]] have less [[mass]] than free [[proton]]s and free [[neutron]]s as [[energy]] is released when the [[nucleon]]s [[Binding Energy|bind]] together.
 : In a [[Particle Accelerator|particle accelerator]], [[Subatomic Particle|particles]] are given so much [[Kinetic Energy Store|kinetic energy]] that when the [[collide]] with [[Subatomic Particle|particles]] travelling the opposite direction much of that [[energy]] can become [[mass]] causing the production of new [[Subatomic Particle|particles]].
