@thattricksta sometimes i would be given something like 50 metres as my lowest sig fig and then i would get something like 1250 N in the answers they would stay at 1250 N this is VCAA btw but the numbers aren't off the top of my head.
Wow the quote warp up before was messed... hopefully you got the part from me
"Being both a chem and physics student, if I was given 2 decimal places to start with I would NEVER throw back 3.
As far as sig figures are concerned in physics I think they only come into play with large numbers where they get you to write 125,000 as 1.25 * 10^5... I have found that trial exams for physics overall are not very consistent with significant figures, but I would try not to give an answer to more decimal places than you begin with..."
I think as far as physics is concerned, I wouldn't worry so much about significant figures but rather decimal points... I'm not sure how wise it would be to give an answer to 3 decimal points if the maximum you start with is 1.
Thats probably the only thing I could think of
