Sig fig rules are sorta straightforward in Chemistry, but what about Physics? (1 Viewer)

^^^^^^^

the same number of significant figures the question's measurements are

cool thanks

Don't forget about the sig figs that are inherent to the data sheet too - like technically gravity is only 2 sig figs.

oh ok - so any calc involving gravity are inherently limited to 2sf?

Physics doesn't really mark for sig figs (as far as I've seen in the marking guidelines for the past few years), however, from what I've heard, sig figs are a 'Band 6 indicator' which just means its a mark of a strong student that they're aware of the accuracy of their calculations. And answering the question above, Yes, any calculations involving gravity are technically inherently accurate to 2s.f. since the value you use is 9.8 (2.s.f) on the data sheet.
