Karten in diesem Stapel (10)
- 1Know how the geocentric model of the solar system dealt with retrograde motionPtolemy introduced equants to the epicycle/deferent system to account for planetary retrograde motion
- 2How is retrograde motion accounted for in the heliocentric model that we use todayretrograde motion occurs when Earth catches up to and then passes another planet
- 3Be able to identify the key orbital positions of planets (conjunctions, oppositions, greatest elongations) and what planets would look like as viewed from Earth
- 4Ellipse
- 5Semi-Major Axisone half of the major axis and equal to the distance from the center of the ellipse to one end of the ellipse. It is also the average distance of a planet from the Sun at one focus
- 6What are the 4 conic sections?circle, ellipse, parabola, and hyperbola
- 7inferior planets equation for sidereal/synodic1P=1E+1S OR 1S=1P-1E
- 8superior planets equation for sidereal/synodic1P=1E-1S OR 1S=1E-1P
- 9Kepler's Third LawP2= 4?^2/G (M2+ M1) *a^3
Only orbit size determines orbit period, NOT eccentricity! - 10—
