(a) show an understanding that all physical quantities consist of a numerical magnitude and
a unit.
(b) recall the following base quantities and their units:mass (kg),length (m),time (s),
current (A),temperature (K),amount of substance (mol).
(c) express derived units as products or quotients of the base units and use the named
units listed in ‘Summary of Key Quantities,Symbols and Units’ as appropriate.
(d) use base units to check the homogeneity of physical equations.
(e) show an understanding of and use the conventions for labelling graph axes and table
columns as set out in the ASE publication SI Units,Signs,Symbols and Abbreviations,
except where these have been superseded by Signs,Symbols and Systematics (The
ASE Companion to 5-16 Science,1995).
(f) use the following prefixes and their symbols to indicate decimal sub-multiples or
multiples of both base and derived units:pico (p),nano (n),micro (μ),milli (m),centi (c),
deci (d),kilo (k),mega (M),giga (G),tera (T).
(g) make reasonable estimates of physical quantities included within the syllabus.
(h) show an understanding of the significance of the Avogadro constant as the number of
atoms in 0.012 kg of carbon-12.
(i) use molar quantities where one mole of any substance is the amount containing a
number of particles equal to the Avogadro constant.
(j) distinguish scalar and vector quantities and give examples of each.
(k) add and subtract coplanar vectors.
(l) represent a vector as two perpendicular components.
