first stage of
star formation
first they are
nebulas
- clouds of
dust
and
gas
(mainly
hydrogen
)
second stage
of
star formation
gravity
causes the
nebula’s
to
collapse
third stage
of star formation
the
collapsed
nebula
is called a
protostar
the
particles
move
quicker
which causes the
temperature
to
increase
to
millions
of
degrees celsius
fourth stage
of star formation
when the
temperature
gets
high
enough the
hydrogen
nuclei
fuse
together forming
helium
nuclei
- this is
nuclear fusion
the
2
opposing
forces
that act on a star
-
gravity
acts
inwards
which can make the star
collapse
-the
energy
from
nuclear fusion
creates a
force
acting
outwards
which can make the star
expand
equilibrium
in a star
the force of
gravity
and the force of
nuclear fusion
are
balanced
