10 Projectile Motion • Homework: • RQ: 3, 13, 16, 18, 20. • Ex: 9, 12, 37.
projectiles • weight-force • air-drag ≈ 0 • “flight-time”: launch speed & angle • “Range” = horizontal speed x flight-time
Kepler’s Laws of Orbits • Elliptical orbits • Equal areas in equal times • Square of year ~ cube of radius
Elliptical Orbits • Speed increases as distance decreases • One side slowing, one side speeding • ellipse shape • simulated orbits
Summary • Range = horizontal speed x flight-time • Kepler’s Laws, speed & distance
