Lesson 1  Newton's Law of Universal Gravitation

apply qualitatively and quantitatively Newton’s Law of Universal Gravitation to:
– determine the force of gravity between two objects ()
– investigate the factors that affect the gravitational field strength ()
– predict the gravitational field strength at any point in a gravitational field, including at the surface of a planet (ACSPH094, ACSPH095, ACSPH097)
Lesson 2  Investigating the orbital motion of planets and satellites

investigate the orbital motion of planets and artificial satellites when applying the relationships between the following quantities:

– centripetal force
– centripetal acceleration
– mass
– orbital radius
– orbital velocity
– orbital period
Lesson 3  The orbital properties of planets and satellites

predict quantitatively the orbital properties of planets and satellites in a variety of situations, including near the Earth and geostationary orbits, and relate these to their uses (ACSPH101)
Lesson 4  Kepler's laws of Planetary Motion

investigate the relationship of Kepler’s laws of Planetary Motion to the forces acting on, and the total energy of, planets in circular and noncircular orbits using: (ACSPH101)
