Space Physics Flashcards
What is the life cycle a low mass star
Nebula
Protostar
Main sequence
Red giant
White dwarf
Black dwarf
What is the life cycle of a high mass star
Nebular
Protostar
Main sequence
Red super giant
Supernova
Neutron and black hole
Why do main sequence remain stable
Gravity inwards is equal to fusion outwards
What is red shift
Moving away
Wavelength increases
Speed increases
How does red shift support Big Bang theory
Expanding universe -dark energy and dark matter
Supernova suggests galaxies are moving away at a faster rate
If temp of protostar increases can form a
Helium nuclei
What are moons
Natural satellites
Why does velocity change but not speed
Force of gravity changes and direction changes
If speed of orbit increases ……
Radius of orbit changes and decreases so gets closer so has more gravity
