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
Albert Einstein
Discovered mass-energy equivalence with the equation E=mc²
Ancient Wisdom
Mass-energy equivalence was long intuited in spiritual traditions as matter being condensed light or divine energy taking material form.
