i have a strong/bad/every feeling that can be described in stress that oscillation and damping ..... the centripetal acc. anyways has oscillations in it..... oh well :tongue:

lool Oye chk yu'r mail :tongue:

yeah i hope they dont change the pattern for the planning question :redface:

...they are the best :biggrin:

Shame we don't have much papers to practice. :redface:

Haha. I am hoping so bad for that too !! Last questions is like the easiest 15-20 marks . If you get that right you are definitely on for an A :tongue:

. All the three past papers seem to have the same repeating pattern(last question) . lets hope Edexcel is nice to us for one more time :biggrin:

does anybody know what the uncertainty for reaction time is? i have heard conflicting answers and it is quite important for any experiment that involves stopclocks.

ive learned throughout my AS never to trust edexcel...they hit back on us like karma :s-smilie:

....yes and ive finally learned how to work out uncertainity ....lets just hope :P

it depends on the question because normally its 0.01s but then if the experiment involves oscillations then its completely a diffrnt case

i've heard that reaction time is 0.1 seconds. however in the specimen paper, it is said that reaction time is between 0.5 seconds to 1 second

Yea there are only 3 pprs for the new Specification

June 10, Jan 11 and the Specimen!
Got june 2010 from scribd.com

damn its annoying that theres not many past papers!
i think that the exponential related questions will come such as discharge of capacitor and nuclear decay...because they normally tell us to take logs and rearrange the equation to y=mx + c so that we can draw a straight line then take the gradient and all....

yeah sorry my bad about that

....check out the attachment file notes and jump to page 4 ..(the highlited part in yellow).... it mentions clearly about time

there is a practical about mass of universe... edexcel can come up with anything they want :eek:

lol Yeah... But don't you think that handout is for the people in the UK who are actually doing the practical ? or is it for international students? :s

Also , Whats are the possible sources of errors in conservation of momentum experiments?

no its for the UK people but we are told to go through just incase :tongue:

... being on the safe side is good :tongue:

...

sources of error for momentum well im not sure for any but the exp says to tilt the runway to copensate friction but again im not sure if we can write this though because they normally ask us to prove whether the track is horizontal :s

Oh thank god ! After looking at the handout got a mini heart attack :biggrin:

Well, I had the same doubt!! In one of the past papers there was a question on how to make sure the track is horizontal . In the teachers guide it says tilt the track to compensate for the friction :s.. Possible sources of error could be the air resistance but its not the best one :tongue:
