Re: A2 Physics Unit 6 ~ 21st May 2012ikr !! this is extremely important !!!!! im actually freaking out from this ! i have a question when we have to find a mean we ignore a very high value right(anomalous result) but when we find our uncertainty (half of range) so in calculating the range do we include that high value or reject it ...?!?!?!?

Re: A2 Physics Unit 6 ~ 21st May 2012I'm trying to do the past-papers; but its sooo hard. God. Bio is way better than this freaking thing.
And plus basically I have to study this by-my-self, because my teacher really sucks. :'( God.
Do you know the % uncertainties equations ? -

Re: A2 Physics Unit 6 ~ 21st May 2012yup they are easy whatdya wanna know ? how to find % uncertainty(Original post by d_94)

Re: A2 Physics Unit 6 ~ 21st May 2012To me, this paper doesnt look any harder than unit 3. But offcourse, you need a lot of practice to master the paper itself. Go through the past papers, correct yourself with a marking scheme. Youll figure out almost all the important-exam-frequent questions.
BTW, does anybody have the past papers for unit 6 from june 2008-june 210? along with mark schemes? please!! -

Re: A2 Physics Unit 6 ~ 21st May 2012Uncertainity? write so heres how it works:(Original post by d_94)
I'm trying to do the past-papers; but its sooo hard. God. Bio is way better than this freaking thing.

Do you know the % uncertainties equations ?
To find the uncertainity of a range of VALUES given:
(Highest value-Smallest value)/2
But sometimes, they might give you just ONE READING, and state the instrument used, i.e 194mm using a metre rule. Uncertainity of a metre rule is +-1mm.
Thus, Uncertainity of measuremnt= 1/194
For % uncertainities, simply multiply the answer by 100.
Assume, a given equation: v=xy^2. where x's uncertainity is negligible. X=12, and Y=30. Y uncertainity is 4. To find the uncetainity of V, as per equation V=xy^2. The steps below:
1. X is negligible.
2.(Uncertainity of Y/ Value of Y)*100=13.33%
3. Multiply this % uncertaity with the number in the POWER. i.e. IF eqtn is y=p^5, power is 5, so multiply by 5.
: 13.33*2= 26.66%.
