* Doc Brown's GCSE Physics Revision Study Notes *

Suitable for GCSE/IGCSE Physics/Science courses or their equivalent

Some notes links are quoted twice in different sub-indexes where appropriate

I am gradually writing GCSE physics revision notes for AQA GCSE physics, Edexcel GCSE physics, OCR (gateway science physics and 21st Century Science physics) exam board specifications.

Links to my new GCSE physics pages will be added to this physics index page AND to the GCSE science/physics pages summarising what you need to know for any GCSE science/physics paper specification (link below).

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 µm 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 µm, 1 m 1.0 x 109 nm, 1 mm 1.0 x 103 µm, 1 cm 1.0 x 104 µm, 1 m 1.0 x 106 µm (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.
