===Meaning===
'''Rest energy''' is the [[energy]] associated with the [[mass]] of a [[Subatomic Particle|particle]] which is stationary relative to the observer.

===About Rest Energy===
: The '''rest energy''' of a [[Subatomic Particle|subatomic particle]] is released in an [[annihilation]] with its [[antiparticle]].
The '''rest energy''' is given by the equation

<math>E=mc^2</math>

Where

<math>E =</math> The '''rest energy''' of a [[Subatomic Particle|particle]].

<math>m =</math> The '''rest mass''' of a [[Subatomic Particle|particle]].

<math>c =</math> The speed of [[light]] (<math>3.00\times10^{8}ms^{-1}</math> in a [[vacuum]]).
