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 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.
