Binding energy
A '''binding energy''' is the negative [[potential energy]] (''i.e.'', energy debt) pulling a bound system together.<ref name = "PotEnIsNeg">[http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/phase.html#c4 Why is the Potential Energy Negative?] ''HyperPhysics''</ref><ref>[[w:Frank Shu|Shu, Frank]].

"Remember, more binding energy means the system is more bound—has greater ''negative'' energy."</ref> Conversely, an '''unbinding energy''' is the positive actual energy required to disassemble a bound system into separate parts.<ref>Pople, Stephen.
