AQA Physics GCSE P2 & P3 [OFFICIAL THREAD]

OP

I predict the grade boundaries to be:

P2: 47/48 A* (54 = 100 UMS)
P3: 45/46 A* (51 = 100 UMS)

C2: 48/49 A* (54 = 100 UMS)
C3: 44/45 A* (49 = 100 UMS)

B2: 43/44 A* (49 = 100 UMS)
B3: 45/46 A* (50 = 100 UMS)

Any modifications are welcome.

Thanks for making this, but I reckon they are all a bit too high

Hi, I didn't round any of my answers for the equations (I just left them as long decimals) will I still get all the marks?

The roots of education are bitter, however the fruit is sweet.

Someone please explain this quote to me before it becomes the new gangnam style. Does I think it means what I think it means

Honestly I have no idea i took it from a website

Thumbs up if you got 'up' for the motor effect question.

Maximum speed was 22.5 and the energy transfered was 612J

and the current was 1.7A not 1.6

Too high for all of them (maybe C2 is spot on though).

i thought conventional current is from positive to negative though??

It is. But when people made circuit diagram, they didn't have an understanding of electrons at the time so they got it the wrong way around.

I'm not really sure what the reason for this was. But when I looked at a past paper the other day, I saw that AQA follow the rule as well.

Go here: http://filestore.aqa.org.uk/subjects/AQA-PH3HP-QP-JUN13.PDF

And check out question 5. The current in the diagram shows to be lowing in 1 direction but its actually the other way around.

Resistance is measured in Ohms
Charge is measured in Coloumbs

Predicted grade boundaries for unit and three??

what did every on get for the "what is one consequence to using nuclear fusion?" question.
and also why is the maximum speed 22.5?

was the left hand rule question on aqa, I don't remember it

i predict the grade boundaries to be:

P2: 47/48 a* (54 = 100 ums)
p3: 45/46 a* (51 = 100 ums)

c2: 48/49 a* (54 = 100 ums)
c3: 44/45 a* (49 = 100 ums)

b2: 43/44 a* (49 = 100 ums)
b3: 45/46 a* (50 = 100 ums)

any modifications are welcome.

i doubt they will be that high

Ahah I was just about to say. All of his were wrong XD Surprised he didn't get put in for the foundation paper

Why would i do foundation when i get an A* in my mock....also im pretty confident my answers are right so i guess we will have to wait.

Ah right okay but i think charge is measured in ohms because that was in my revision notes and i read it loads, im still pretty sure the answer is 17m/s?? Also i know the current was 1.6 because you had to look at 0.01 seconds (that is probably where you went wrong!)

I still think i can get an A* but it will probably be harder now

yeah I think 17m/s is correct aswell but I highly doubt it because many other people have got 22.5m/s. Current is sadly measured in amps not ohms so I think you may have written it down wrong and revised the wrong thing. As for looking at 0.01s, I'm pretty certain you're wrong. It asked you to look at 0.1s and then find the current :L

am I the only one who got 25 m/s for speed on p2?

I got the gradient was steepest near the end, so did 50/2, for vertical over horizontal

Max speed one was 22.5 m/s
GPE and KE one was 3.6J
Momentum question was 5 m/s
Energy transferred was 612J
Charge was 51 C/coulombs
Current was 1.7A

Omg you're right- they're so similar!

didn't do unit 3 so im not able to offer my views on that one, but im thinking the grade boundaries for unit 2 will be approximately:
B2 42/60
C2 48/60
P2 46/50
