You will need to use a combination of the materials we have collected here to enable you to succeed. The most important factor will always be your effort. Use the knowledge of your teacher, attend revision sessions, ask when you need help. Most importantly of all, stay confident! You can do this!

Learning Checklist & Knowledge Organiser

4.8.1 Solar system; stability of orbital motions; satellites

List the types of body that make up the solar system and describe our solar system as part of a galaxy
Explain how stars are formed
Describe the life cycle of a star the size of the Sun and of a star which is much more massive than the Sun
Explain how fusion processes lead to the formation of new elements and how supernovas have allowed heavy elements to appear in later solar systems
Explain that, for circular orbits, the force of gravity leads to a constantly changing velocity but unchanged speed
Explain that, for a stable orbit, the radius must change if the speed changes
