Appendix 1 - 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;

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 The numbers game! 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.!)

Numerical prefixes you should know for your gcse science-physics courses

10n Prefix 10n Prefix
1024 yotta 10-1 deci (d)
1021 zetta 10-2 centi (c)
1018 exa 10-3 milli (m)
1015 peta 10-6 micro ()
1012 tera (T) 10-9 nano (n)
109 giga (G) 10-12 pico (p)
106 mega (M) 10-15 femto
103 kilo (k) 10-18 atto
100 (none) 10-21 zepto

Another numbers game that can cost you marks in an exam!

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 other 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.
