Textbook reading: Read Walker section 12-1 on pages 379-380. Pay special attention to the material between the red lines on page 379. Skip the last paragraph on page 380, which begins “Finally, if a given mass…”
Pre-reading question: Star Alpha and Star Beta have the same mass, m, and their centers of mass are separated by a distance d. What would happen to the force of attraction between the stars if Star Beta doubled in mass?
Note: in this video, I mistakenly say 30+24=59. That is clearly incorrect. 30+24=54
