APPENDIX 1

Most GCSE physics courses will expect you to know and be able to use the following units

Be able to recall and use the following SI units:

metre, unit symbol: m;   kilogram unit symbol: kg;   second unit symbol: s

ampere unit symbol: A;  kelvin unit symbol: K;   mole unit symbol: mol;

AND some derived units with special names: name unit abbreviation:

Frequency hertz Hz,  Force newton N, Energy joule J, Power watt W,

Pressure pascal Pa, Electric charge coulomb C

Electric potential difference volt V,  Electric resistance ohm Ω,  Magnetic flux density tesla T

Be able to recall and use multiples and sub-multiples of units, including:

giga (G, 109),  mega (M, 106),  kilo (k, 103), centi  (c, 10-2),  milli (m, 10-3),  micro (μ, 10-6)  and  nano (n, 10-9)

Be able to convert between different units, including hours to seconds.

Be able to use significant figures and standard form where appropriate


APPENDIX 2.

Using numerical equivalents

e.g.: 1 m 10-6 m, 1 nm 1.0 x 10-9 m, 1 mm 1.0 x 10-3 m, 1 cm 1.0 x 10-2 m,

1 m 1.0 x 106 m, 1 m 1.0 x 109 nm, 1 mm 1.0 x 103 m, 1 cm 1.0 x 104 m, 1 m 1.0 x 106 m (etc.!)


APPENDIX 3.

Significant figures and what is legitimate to quote for a final numerical answer

Since many sections of physics involve calculations, significant figure quotation should follow the rule:

Significant figures (s.f.) is the limit of numerical accuracy you can be sure of e.g.

If the data numbers in a question are 20, 25, 0.125, 678, 1.234, you can only quote the final answer to the nearest 2 sf - dictated by the 20 (only quoted to 2 s.f.) even though the data is quoted to 3 or 4 significant figures..

If the question data said 20.0, you could still only quote the final answer to 2 s.f. because of the 25.

If the question data said 20.0 and 25.1, you could then quote the final answer to 3 s.f.

Any intermediate working is not governed by this convention, only the final answer to a specific calculation.
