1. Early Explanations for Planetary Motion

2. Copernicus� Heliocentric Model Destabilization of Aristotelian/Ptolemaic worldview What is mechanistic explanation for planetary motions?

3. Two aspects to questions about gravity

Planetary motion

Planetary motion. Watching the sky night after night, month after month, some “stars” appear to move Planetary motion is much slower than diurnal motion Five “wandering stars” known to ancient people were Mercury, Venus, Mars, Jupiter, and Saturn. Greek Astronomy (Aristotle &amp; Ptolemy).

Planetary Motion

Planetary Motion. Planetary Orbits. Two forces work together to keep objects in the universe in orbit. Inertia. Inertia – Objects in motion stay in motion, objects at rest stay at rest unless acted upon by an outside force. Gravity.
