WJEC AS A2 Physics 2009 and 2010
This section of the website contains
suggestions for material that could be used with the WJEC Physics AS and A2 Specification
(2009 and 2010).
WJEC is not affiliated with the author of the site and has had no
involvement with the content of this website.
The website does not necessarily
cover all topics or to the correct depth required for this specification although some sections
may cover topics in more detail than is needed. It is the responsibility of the individual
teacher to select the appropriate material.
References to work from the GCSE
section of the site that would be useful atAS/A2 level are shown as (14-16) or (11-
14)
I am grateful to WJEC for permission to reproduce adapted versions of text from
their Physics GCE Specification on this site.
