Measurements equations

The one equation the measurements notes display, with a link to the lesson that states it. The AQA data booklet does not print it, so it is one to carry into the examination in your head.

The marks refer to the AQA 7408 data booklet. An equation it prints is marked as such, and one it leaves out is marked to learn. An equation with no mark has not been checked against that booklet, and some of these belong to the Edexcel, OCR or CIE specification rather than AQA’s, so check them against your own board’s data or formula booklet.

Uncertainty and error

Every equation in the library is indexed by unit on the equation index, and the measurements notes are where these equations are derived and used. The one the booklet leaves out is on the equations to memorise, alongside the rest of the course.
