Significant digits on AP Physics B exam?

Question

On the free response portion of the AP Physics B exam, are the graders sticklers about significant digits, or do they not care? If so, which rules for significant digits do they use? If not, are there any hard-and-fast rules for how many decimal places answers should be reported to? Thanks!

Answer 1

I would say that as long as you use a reasonable number of digits, you should be fine. You need to remember that only a small number of points are awarded for a correct answer. It is the correct process that they are looking for. You could write down the right answer, but if you have no work to show how you got to that answer, you will not receive a lot of points. Even if you mess up the significant figures, with the right work, you will receive the majority of the points for the problem.

Answer 2

I've taken both B and C exam, and in both I've never actually cared much about the significant digits and I've gotten 5's on both of them, so I'd say they don't really care. Generally rounding answers to the nearest thousandths would be OK.

Answer 3

I took it too. The assorted determination i got here upon fairly confusing by way of fact of time (I basically have been given to question 60 and guessed on the final 10). i theory the extremely some loose reaction questions have been flipping hard it gave me a headache. i think of I did nicely on a minimum of three-4 of the loose reaction questions
