# Edexcel A2 Physics Unit 5 'Physics from Creation to Collapse' watch

How will you get the marking scheme?
From my glorious teacher
2. (Original post by JayAyy)
Most people found that really difficuly. 47/80 would be a good prediction if it was hard as everyone said it was. (The lowest it has been was about 45/80 or something like that).
yeah, everyone in my centre told it was ******* hard, but in TSR everyone said it was easy, so I thought, ............................... it would be high?

I DID THE SAME F******* MISTAKE ;(
No but didnt it say it moves a max 70 mm from the equilibrium position
4. oh people,people,

The sun and fussion question,what are the conditions for fussion?

Some people on here said it was difficult (which is a surprise). Low boundaries for Unit 4 is my prediction

Are you sure?????

No it will definetely not be high,if you see the grade boundaries even from ridiculously easy papers (unit 2 june 2009),they were low.

But this paper was full of theory,and not all the people doing it have english as their mother tongue.

no,i am pretty sure it said total distance was 70mm

High temperatures and high densities
I put pressure instead of density though

lets hope.

I too put something like that and mentioned hydrogen and helium too.
and defined nuclear fusion.

i put lighter unstable nuclei combine to make a heavier,more stable one and a lot of energy is released,and because many fussions take place each second,the sun has lots and lots of energy
13. How can I forget to mention hydrogen and helium?

And not all ppl who have English as their mother tongue answers theory question well.
About 60-65. It wasnt hard at all I think.
I did divide that total distance by 2 for the bridge's amplitude.

Well, since it was placed vertically first
f = 1/T
T = 2п√(m/k)
F = ma = -kx
a = g = 9.81
m = 0.15
x = 0.2
Not really sure about the numbers.
It could be done a bit different way.. I did both.
Ohhhh a=g. I KNEW there was some variable I should've been able to figure out. I still don't get the wording of the question though and wtf Katie Melua? Great thanks for giving me that song in my head

A relief after FP3.

ETA: I noticed the G units were wrong before the exam (Edexcel didn't :O) and those * questions where you get a mark for wuality of writing seem to come on calculation questions or on a 3marker? In unit 4 in jan they were on 5 markers?

Are you serious?
17. (Original post by Pegasus92)
Are you serious?
I probably did, but at the moment I can't remember if I did or not.

Now lets all pray

I don't think it matters that was one of the star questions I mentioned above so 2 marks for answer, 1 for communication. I think density=1,temperature=1,quality= 1
20. (Original post by JayAyy)

DAMN. I missed out the high density part. I think I did put something about there needed to be high gravitational forces to do work on the particles, therefore giving them very high temperatures.

I thought it was... IDK. Some parts very difficult, not because I didn't know how to do them, but the questions were so left of centre. Just odd questions.

And the Katie Meluda one was a bizarre way to link in something irrelevant to stuff they wanted answered!

And was anyone else annoyed that they had made a mistake on the exam paper AGAIN! Mistakes on another unit this summer, mistakes in the sample paper, mistakes on the actual paper.... Edexcel, get your act together.

I'll admit... I'm very... ordered, I guess. I like an order to things. It keeps me calm. You break the pattern with 'there is a mistake here btw', I freak out a bit.

So, yeah. I'm just not very impressed with Edexcel's Physics department. Their maths department I have no complaints about. They are awesome, very clear and helpful. But their physics stuff just seems half-assed.

Fancy having to rectify TWO mistakes on the papers in one period?
