Learning Objectives

1. Understand the fundamental forces of gravity, electromagnetism, and the nuclear force, and their interplay on large and small size scales.

2. Visualize the fission process.
   • Comprehend how the fusion process acts to divide unstable (radioactive) nuclei.
   • Connect the difference in mass between the initial reactants and the final products to the energy emitted.
   • Evaluate the importance of fusion within the Sun by considering the amount of available radioactive materials in the core.

3. Visualize the fusion process.
   • Relate the temperature and pressure within the solar core to the probability that two protons can join (fuse).
   • Connect the mass lost in the fusion process to the emission of energetic gamma rays.
   • Quantify the amount of hydrogen which must undergo fusion every second in order to power the luminosity of the Sun.
