2.6.2 Nuclear fusion
a) Nuclear fusion is the joining of two atomic nuclei
to form a larger one.
b) Nuclear fusion is the process by which energy
is released in stars.
c) Stars form when enough dust and gas from space
is pulled together by gravitational attraction. Smaller
masses may also form and be attracted by a
larger mass to become planets.
d) During the ‘main sequence’ period of its life cycle
a star is stable because the forces within it are
balanced.
e) A star goes through a life cycle. This life cycle is
determined by the size of the star.
GCSE Physics for certification June 2014 onwards (version 1.1)
f) Fusion processes in stars produce all of the
naturally occurring elements. These elements may
be distributed throughout the Universe by the
explosion of a massive star (supernova) at the end
of its life.
Suggested ideas for practical work to develop skills and understanding include the following:
■ using domino tracks for fission/chain reactions.

Additional guidance:
Candidates should be able to explain how stars are
able to maintain their energy output for millions of years.
Candidates should know that elements up to iron are
formed during the stable period of a star. Elements
heavier than iron are formed in a supernova.
