MODELS OF THE SOLAR SYSTEM Chap. 29, Sect. 1 OBJECTIVES: SWBAT… 1. Compare the models of the universe developed by Ptolemy and Copernicus. 2. Summarize Kepler’s 3 laws of planetary motion.

EARLY VIEWS OF SOLAR SYSTEM 1. Earth is center: geocentric theory. (Aristotle) 2. Earth is flat and motionless.

GEOCENTRIC THEORY

EARLY VIEWS OF SOLAR SYSTEM 3. Greeks: planets move in reverse direction (retrograde motion).

RETROGRADE MOTION

CLAUDIUS PTOLEMY

EARLY VIEWS OF SOLAR SYSTEM 4. Ptolemy: “planet has 2 motions”: A. one is around the Earth. B. one is on a smaller circle (epicycle).

EARLY VIEWS OF SOLAR SYSTEM C. explains retrograde motion.

EPICYCLES

NICHOLAS COPERNICUS

RISE OF MODERN ASTRONOMY 1. Copernicus: A. “sun is the center” B. “planets move at a different speed and direction, which explains retrograde motion.

COPERNICAN VIEW

TYCHO BRAHE

RISE OF MODERN ASTRONOMY 2. Tycho Brahe: A. uses 1 st pretelescopic instruments. B. charts over 700 stars in precise positions.

JOHANNES KEPLER

RISE OF MODERN ASTRONOMY 3. Johannes Kepler: A. analyzes Brahe’s data. B. comes up with 3 Laws of Planetary Motion.

RISE OF MODERN ASTRONOMY LAW 1: “The motion of a planet around the sun is an ellipse (oval-shaped).” A. sun occupies 1 foci. B. perihelion and aphelion.

LAW OF ELLIPSES

RISE OF MODERN ASTRONOMY LAW 2 (Equal Areas): “A line drawn from a planet to the sun sweeps out equal areas in equal amounts of time.”

LAW OF EQUAL AREAS

RISE OF MODERN ASTRONOMY LAW 3 ( Law of Harmony): “The cube of the ave. dist. Of a planet from the sun is always proportional to the square of the period.” K x r 3 = p 2

NEWTON’S LAWS Said that a moving body will change its motion only if an outside force causes it to do so. Inertia: the tendency of a moving body to move in a straight line at a constant speed until an outside force is applied.
