Nuclear Physics
Learning Objectives
- Students will be able to explain nuclear fission and fusion processes
- Students will be able to calculate binding energy and mass defects
- Students will be able to understand Einstein's mass-energy equivalence
Core Concepts
- Nuclear fission
- Nuclear fusion
- Binding energy
- Mass defect
Formulas
$$E = mc^2$$
Mass-energy equivalence
$$BE = (Zm_p + Nm_n - m_{nucleus})c^2$$
Binding energy from mass defect
$$\Delta m = m_i - m_f$$
Mass defect in nuclear reactions
Units
| Mega-electron volt | MeV |
| Atomic mass unit | u |
Interesting Fact
A small amount of matter converts to enormous energy according to E=mc²: 1 kg of matter = 90 TJ
Key Scientist
Enrico Fermi
Achieved the first controlled nuclear fission reaction
Modern Research
Nuclear fusion research at the National Ignition Facility achieved net energy gain, advancing toward practical clean fusion energy for civilization.
