- space physics
- life cycle of star
- cloud of gas and dust (nebula)
- gravity pulls stuff together. hydrogen collide forming helium, there is lots of energy. this is a protostar
- long stable period, main sequence star
- small stars expand forming red giants
- the red giant ejects dust and gas, becoming a white dwarf
- it cools down and has no energy and becomes a black dwarf
- the red giant ejects dust and gas, becoming a white dwarf
- large stars expand becoming a super red giant
- they give off lots of light/energy in an explosion called a supernova
- supernova becomes a black hole if its big enough
- supernova throws gas and dust everywhere leaving a dense core called a neutron star
- they give off lots of light/energy in an explosion called a supernova
- small stars expand forming red giants
- long stable period, main sequence star
- gravity pulls stuff together. hydrogen collide forming helium, there is lots of energy. this is a protostar
- cloud of gas and dust (nebula)
- the solar system
- planets: things that orbit a star
- dwarf planets: small planets
- moons: things that orbit planets (natural satellite)
- artificial satellites: man made things that orbit a planet
- orbits
- when object is pulled around something by gravity
- the objects are constantly accelerating towards the planet
- instantaneous velocity is perpendicular to the acceleration so it goes in a circle
- speed of orbit
- smaller radius means faster speed
- larger radius means slower speed
- life cycle of star
