What this unit covers
- Solar system; stability of orbital motions; satellites: (Physics only) State that the Sun is a star.
- Solar system; stability of orbital motions; satellites: (Physics only) State that the Sun is one of many stars in the Milky Way galaxy.
- Solar system; stability of orbital motions; satellites: (Physics only) State that the temperature rises as the protostar becomes denser.
- Solar system; stability of orbital motions; satellites: (Physics only) Describe a star as forming from a cloud of dust and gas called a nebula.
- Solar system; stability of orbital motions; satellites: (Physics only) State that for a stable circular orbit the speed of the object is constant but its velocity changes.
- Solar system; stability of orbital motions; satellites: (Physics only) State that gravity provides the force that allows planets and satellites to maintain circular orbits.
- Red-shift: (Physics only) Explain that more distant galaxies show a greater red shift.
- Red-shift: (Physics only) Explain that the observed expansion of the universe supports the Big Bang theory.
- Red-shift: (Physics only) Use the Milky Way as an example of a galaxy.
- Red-shift: (Physics only) Link galaxy observations to evidence for expansion of the universe.
