PHYSICS Y9, Space, Radioactivity - Coggle Diagram

- - - - A also means current or 'Amperes'
    - - or 'Coulomb'
    - - PD can also mean 'Current'
    - - V in an electrical circuit means 'Voltmeter'
      - V overall can also mean Potential Difference, interchangeable with PD
    - - Work Done can also be exchanged with 'E'
- - - - Protostar
        
        Main sequence star
        
        Then stars much larger than the sun turn into:
        
        Red super giant
        
        Supernova
        
        Black Hole
        
        Neutron Star
        
        Then stars the size of the sun or smaller turn into:
        
        Red Giant
        
        White Dwarf
        
        Black dwarf
- - - - Planets and moons
        
        Planets orbit a star, moons orbit planets
      - Moons and artificial satellites
        
        Moons are naturally made, artificial satellites are not
      - Planets and artificial satellites
        
        Planets are primary bodies, artificial satellites are secondary
        
        Orbit height, planets orbit much further from their star than artificial satellites from their planets
    - - Planets and moons
        
        They both orbit a larger object
        
        They both take roughly 365 days to do so
        
        Both orbit clockwise
        
        Both orbit in the same circular fashion
      - Planets and artificial satellites
        
        They both follow an orbital motion
        
        The both have a stable path
      - Moons and artificial satellites
        
        They have the same velocity
        
        They both follow the same orbital motion
