Solar Nebula and Keplerian Motion: walkthrough

Section role: supports the 'Synthesis of Orbital Mechanics and Formation Theory' section while the teacher transitions students from raw mission data to formal astronomical laws. Slides: (1) Title — 'From Data to Theory: How Our Solar System Formed'; (2) The Solar Nebula Hypothesis — bullets: gravitational collapse of a giant molecular cloud, flattening into a protoplanetary disk, conservation of angular momentum; (3) Accretion Process — bullets: collision and sticking of dust grains, planetesimals, protoplanets; (4) The Frost Line — bullets: temperature threshold in the nebula, rocky materials inside, volatile ices outside; (5) Terrestrial vs. Jovian Split — connection back to the mission dossiers on Mars, Venus, Europa, and Titan; (6) Kepler's First and Second Laws — bullets: elliptical orbits, foci, equal areas in equal times; (7) Kepler's Third Law — formula P2 = a3, connecting orbital period to semi-major axis; (8) Application Example — calculating orbital periods using Astronomical Units (AU); (9) Vocabulary Review — Nebular Hypothesis, Frost Line, Accretion, AU; Closing slide: 'How does the frost line explain why we found liquid oceans on Europa but not on Venus?' — hands control back to the teacher for the verification assessment.
