Information relating to all achievement standards

Formulae and the value of the physical constants needed for these standards will be provided in a separate resource sheet that will accompany the examination papers.

Candidates should show their reasoning clearly and may use numerical working, words, and / or diagrams.

Mathematical solutions at the Excellence level will require candidates to show, mathematically, that two phenomena, concepts, or principles are connected.

The acceleration due to gravity will be given as g = 9.8 m s-2.

The number of significant figures in any answer should be consistent with the data in the question.

Answers should be given with an appropriate unit. SI units should be used unless it is more appropriate to include a prefix (milli, kilo, and others will be given). Candidates are expected to understand the prefixes micro, milli, centi, kilo, mega.

Equipment

Candidates require a calculator, a ruler, and a protractor.

Specific information for individual achievement standards
