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. For the full version of the specification please see: WJEC AS and A2 Physics 2009/2010
