1. How does angular momentum affect
a nebula that is contracting inwards.
2. According the equation for gravity, what
are the 2 factors gravity is dependent on:
4. Which direction
does gravity pull?
5. Which direction does the solar system spin?
Johannes Kepler
Kepler, was the first astronomer
to mathematically prove
Copernicus’s new heliocentric
model was possible.
6. Draw a Heliocentric model:
7. How is this the opposite from a
Geocentric model?
Since geometry is
co-eternal with the
divine mind before
the birth of things,
God himself served
as his own model in
creating the world.
Johannes Kepler,1618
