Atomic + NuclearBinding energy, fission and fusion

1 Binding energy and mass defect raise object and ask how p.e. of Earth-

object system changes [increase] show model He nucleus and ask how p.e.

changes when separate nucleus into 4separate nucleons [increase] how does p.e. change when bring 4

nuceons together to form nucleus[decrease]

E=mc2so drop in energy accompanied bydrop in mass

!E= !mc2

binding energy = (mass defect) x c2
