OCR AS A2 Unit 1 Mechanics
This section contains
suggestions for material from the schoolphysics website that could be used with the OCR Physics A AS A2
Specification (first examination in 2009 and 2010).
OCR 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 at GCSE level that might be useful
at AS level are shown as (14-16) or (11-14)
