(a) show an understanding that all physical quantities consist of a numerical
magnitude and a unit.
(e) show an understanding and use the conventions for labelling graph axes
and table columns
(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
(h) show an understanding of the significance of the Avogadro constant as the
number of atoms in 0.012 kg of Carbon-12.
(j) distinguish scalar and vector quantities and give examples of each.
(l) represent a vector as two perpendicular components.
(a) use techniques for the measurement of length, volume, angle, mass, time,
temperature and electrical quantities appropriate to the ranges of
magnitude implied by the relevant parts of the syllabus.
In particular, candidates should be able to:
(3) measure an angle using a protractor.
(4) measure time intervals using clocks, stopwatches and the calibrated
time-base of a cathode-ray oscilloscope (cro).
(6) use ammeters and voltmeters with appropriate scales.
(7) use a galvanometer in null methods.
(9) use a calibrated Hall probe.
* (b) use both analogue scales and digital displays.
(d) show an understanding of the distinction between systematic errors
(including zero errors) and random errors.
(e) show an understanding of the distinction between precision and accuracy.
