Physics paper 5 : Help needed urgently

[MaNi_DaDuDe]

Thanx Alott for all the resources...Please forgive me, I was a little agitated...its just that i have a physics mock tomorrow and , well you all can imagine the anxiety esp if u haven't prepared well

i have mine on wed. haven't prepared at all.

i understand error bars and how to get the error ithe gradient. what i dont know how to do is get the error in other things .. like for ex nov 08 q2.d .. and they dont even have the answer in the mark scheme what do i do ?

[Hwa1]

Just under 15 hours til exam....I hate this so much...too much error rubbish -.-

I LOVE ERRORS!
i love all the math parts. the physics parts... notsomuch

they do tell you how to do it in the markscheme..
e/m from your gradient - e/m from worst acceptable line gradient

personally i would've done this by calculating the percentage error of the gradient, which is equal to the % error in e/m, then multiplying it by whatever value i got for e/m.

What other way is there? =/

What other way is there? =/

according to the markscheme,

e/m from your gradient - e/m from worst acceptable line gradient

Ahhh ok gotcha, thanks

I'm still worried to death....I think right now I'm on the borderline of an A so i really have to do well in this paper....
No A >>> bye bye uni offer

LOL, i'm just hoping i'll maintain my B. i totally messed up on paper 4 so
don't worry, this paper's easy.
