its always the case.... to make a levels more 'assceble'(spelt) to others.... basically so more people do physics
For an A grade in unit 1 January 2005 AQA B spec, you needed 46/75 i think, which is only 61%!!! still, no one in my entire year got above 65% (I got 64%, I do not know where about 10-15 marks went, after going through the paper :confused: )

They do it because people tend not to do well on Physics papers...In my school, last years year 12, out of 26 people doing AS level physics, 19 people got an E grade or worse...are teachers are useless >.<

scary stuff!!! making me scared for my A2's lol - i'm counting on last minute revision to see me through:smile:

make physics more accessible - how much easier could they make - its a doddle compared to maths - hould have seen thyey physics stuff back in the days :rolleyes: was well hard back then!

:eek: i do maths and phy and i think maths is way easier than physics. mybe cos i got crap teachers for physics but i find its much harder, esp that u can learn a whole revision book for phy and yet find the exam hard :frown:
(or is that just me :redface: )

ell phyiscs is maths and physics you need to calculate and explain while in math you need to calculate though harder calculation still me thinks physics is harder somehow :frown:

Nope, is me aswell :P maths is a good deal easier than physics, and my physics teachers are rubbish, one of them spends about 1/6th of the lesson teaching, 5/6 lesson pratting about, talking, joking, walking off et cetera

does this apply to all exam boards?
Does anyone have detials of the grade boundaries (raw mark) for OCR Physics (Spec B)?

my physics teachers are **** too...spent a year trying to get this bugger changed cos my uni depends on it, to no avail...i decided to go to lessons for the EMA - don't listen to any rubbish he speaks and teach myself at home...got a new textbook just for that purpost, lol.

Oh, and the maths in physics is easy...but the defining terms, and describing experiments is what i find hard - that is just so weird...and wave-particle duality - what is that about!
They have cut all the Alevel standard maths out of physics, so more people do it. Which is pretty pointless because most people that do physics do maths too!
Even though the maths in physics is relatively easy, I think those that dont do Alevel maths with it will stuggle a bit.

I totally agree with difficulty in explaining priciples. You have to get your english and the terms perfect to get the marks. I really hated explaining the newtons laws stuff, in PHY1, which is why I still think PHY1 is the hardest module of the syallbus!!

im retaking phy 1 , got it on friday and i still aint begun revisin for it. I cant remember much from last june aswel :eek:
i was hoping i will spend maybe 1 or 2 days on it max and get hopefully a gd A, maybe i should spend more time on it than that ? ( but its on friday and i got other stuff to revise for aswel :mad: )

you on study leave? if so start on thursday morning and work on only it till your exam, and if not then i'd say start on tues evening, wednesday:smile:

its possible...i revised AS physics in two days, and 1/2 A2 physics in teh same time:smile:
I think wave-particle duality is to do with the fact that theories proposed by Liebniz/Newton about waves as particles, only fit with theries about light being waves made by Huygens, and vice-versa...that is relatively fun physics.
edit: not saying I totally understand it though!!
I can not stand the nature of information chapter, and uses of waves et cetera, particle physics is cheese

can anyone tell me how standardising works (edexcel)
im doin phy1 2morow and need to gd grade, the only hope ve got is if i do well and its stadardised to a gd A ?
and also ive seen people with full marks in all units, how does that happen, do u get stardarised to 100% if u get a certain % or are they just super brainy ?
thanks

its all based on standard deviation, you can get full UMS score without actually gettin full marks, if everyone gets half marks for instance, you get full marks!, it all depends on what the overall studnets get
Can Anyone Answer this question and explain it!!!!!!!!!
A laboratory lead consists of 16 strands of fine copper wire twisted together. Each strand is 30 cm long with a diameter of 0.15 mm. Calculate the potential difference across the lead when it is carrying a current of 2.0 A.
(The resistivity of copper = 1.7 × 10–8 Wm).

You just need to use R = (rho X l)/a where R is resistance, rho is the resistivity, l is the length and a is the cross sectional area. You need to convert the length and diameter to metres before putting the values into the formula & then you're done! : ) For the cross section area as you have 16 of the wires the area is going to be 16 times the diameter of one of the strands, and the length is still 30 cm.

If you're still not sure, this explains it well:

Once you have the resistance value, just put it into the formula I = V/R (just rearrange V=IR)

(I would do the calculations, but I have physics AS tomorrow & have loads of past papers to do :|)
