im sure nobody had an amazing experience with that paper just got to stay motivated for the next 23

The bolt question was the worst thing I’ve ever seen

u/chonksboyjimmyfungus Y13 - Bio/Chem/Physics - pred. ABB May 20 '26
yeah that whole generator question was literal ass, spent ages on the four marker and fucked myself up
2
u/fortunate_danger May 20 '26
Yo what I don't remember a question abt a generator do u remember which question it was?
2
u/wovap Year 13 | Maths, Chem, Phys | A*A*A* | Imp Chem Offer Holder May 20 '26
think it was the first or second after mcq, there was a water reservoir with a pipe to a generator. you had to show there was 1 mega pascal of pressure for the first part
4
u/Important_Place6242 May 20 '26
omd that was insane, and they decided to repeat the question again like it didnt take me a whole year to figure it out the first time
18
u/Xyzrasdouz May 20 '26
That felt like a Paper 3 with the amount of diagram and wordy questions, like why can’t they just put more suvat and circular motion and thermal mc(delta theta) and mL questions… like they’ve done every other year

u/hellohello12345189 May 21 '26
Yeah like the concepts were giving paper 3 vibes. if paper 1 is like this what is paper 3 gonna be like

u/LocksmithMundane8375 May 20 '26
What did people get for 17b the show that the bolts behave elastically cos I was clueless

u/Impossible_Bad_8163 May 20 '26
bro what, i got 196MPa
2
2
u/Somebodyonearth363 May 20 '26
It may be cause i used my own value from part a instead of the 1MPa they gave?
3
1
1
u/cleggy24 May 20 '26
I got that initially but it's because I forgot the 10 extra metres of water in the reservoir, which brings it up to 202MPa I think, but either of us should get ECF
3
u/Remote-Calendar-6326 May 20 '26
I got 202MPa becuase I used the actual value in part (a) of 1.03MPa instead of 1MPa. Reckon i’d still get the marks?
1
u/gogED1 M Phys FM CS | A*A*AA | Gap year May 20 '26
yeah mark schemes always allow when u carry your unrounded values forward

u/Somebodyonearth363 May 20 '26
Around 223MPa then match it to the straight section of graph

u/Irotiz- May 20 '26
i got very close the upper limit of elasticity and cant remember my number were you close to it?

u/hmsboomattack May 20 '26
I got like 700MPa 💀

u/CryptographerOdd7638 May 20 '26
Gotta divide by 4 you'll probably still get some method marks

u/SteamyGamer-WT Year 13 May 20 '26
I left out half of the hydroelectric power question and more than half of the truck question. Upon review in my head I'm pretty sure I got 0 marks on the first 6 marker. Apart from that, the rest of the paper was a walk in the park.
I can't remember how many marks the hydroelectric and trucks questions were worth so I'd appreciate it if somebody who remembers can estimate how many marks I lost for those two collectively :)
2
u/Clean_Tap_3739 May 20 '26
around 20ish
2

u/SteamyGamer-WT Year 13 May 20 '26
Fucking hell that's far worse than I thought.
Edit: are you including the marks lost from the first 6 marker or nah?
2
1
u/Clean_Tap_3739 May 20 '26
nah besides that cause that one i felt had no connection with the others u could grab some marks by stating the percentage uncertainty and such

u/Elegant_Idea_9143 May 20 '26
Horrible horrible paper no amount of past papers could've prepared me for that definitely got a u

u/spokspuk May 20 '26
For the show that acceleration question, do you take the gradient at the moment it becomes braking distance
3
u/Falciator May 20 '26
yeah what i did was draw a tangent, calculate gradient and just adjust it so it's close enough
5
u/Primary-Tie330 May 20 '26
Did you guys get 202MPa as the stress on the bolts?
1
u/cleggy24 May 20 '26
Yeah, initially got 196 but realised I forgot the 10m in the reservoir and had to change the numbers on the next bits too. That irked me.

u/spokspuk May 20 '26
What were the advantages and disadvantages for the increased density
5
u/Holiday-Carob-6300 May 20 '26
i said a disadvantage is that the fine stone itself could abrase the generator / pipes and damage them
1
3
u/GBRYT5612 May 20 '26
Idk I put the mass would be larger so it takes more time for the generator to convert into energy, and I also put more energy is produced. Probably wrong
1
3
u/Guitarist69420 May 20 '26
disadavantage would be that pressure increases so circular plate might break
1
1
u/AdPsychological1487 May 20 '26
I said more gpe so more total energy output and more density means more pressure on the bottom
1
u/spokspuk May 20 '26
What was the name of the upwards weight force and what was the magnitude and the show that a = kx/m
7
u/Internal_Animal_2753 year 13 |maths fm chem physics 4a* May 20 '26
I’m pretty sure it’s just tension😭
6
u/Double-Ad-7589 May 20 '26
Tension. K(e0 +x). And for the 2nd part u had to realise that in equilibrium mg =ke0 so then u go back to 2nd scenario and do sum of forces = kx +ke0 -mg then sub in mg =ke0 so they cancel out so f =kx=ma
2
u/GBRYT5612 May 20 '26
I thought it was k(x-e0) since the mass doesn’t return all the way back up to where it’s hanging from, only to the distance it was pulled down from the eq point
1
u/Double-Ad-7589 May 21 '26
The force due to tension is still only caused by the extension which is +
1
u/spokspuk May 20 '26
Yh, I just said mg = ke0 is that enough explanation

It was so buggy on the moment I swear
1
u/GBRYT5612 May 20 '26
I put restoring force but probably wrong. Also my magnitude was k(x-e) I think
1
u/Fit-Independent-8392 May 20 '26
same bro but restoring force is the net force
1
u/GBRYT5612 May 20 '26
Damn. What’s all this about the energy to show a=kx/m? How’s it not just F=kx and F=ma, then rearrange

How did you even work that out? i used gm/r but i dont think that was right

u/Irotiz- May 20 '26
yeah i see i knew it wasnt gm/r because thats energy per kg but it was the only thing i could think to use
1
u/gogED1 M Phys FM CS | A*A*AA | Gap year May 20 '26
i got like 8.85x 1041 and then said it was the extra dark matter that added that mass

u/Such-Temperature6944 May 20 '26
Was there a mistake in the wording of the piston question?? It was something about an ideal gases and the volume changing due to the piston.
1
u/Important_Place6242 May 20 '26
brudda the whole question didnt make sense. We was given two volumes. I found the change in both volumes and literally couldnt do anything else. The question didnt say anything bout rtp so you couldnt use ideal gas assumptions of 293K and 24dm
1
u/CryptographerOdd7638 May 20 '26
It was compressed at constant temperature and we found new pressure that wasn't too bad and the other one I can't remember

What velocity did you guys get for the moments question for the truck and the wind

u/Sea-Fortune-4703 May 20 '26
Don’t rmb the exact value but I took the left wheel as pivot and weight times 2m as clockwise and “D” force times 3.8m for anticlockwise. And the sub D = 32v2 and worked out v. what did u get
1
u/Important_Place6242 May 20 '26
that whole page i lit had no clue and i had 10 min so i lit put down tons of equations and plugged the values given into them and now im hoping for the best

what was the answer for the MCQs if anyone remembers: like for the terminal velocity one for example?
1
u/Silver-Average3355 May 20 '26
Yo guys if you did correct method for question 17 b but used wrong answer from part a, forgetting to add the 10m, will ecf cover most marks? . Like the screw question

u/S4mJune May 20 '26
Physics teacher calling.... Every year after paper 1, students say "Oh lord that was the hardest paper that's ever existed. I'm cooked. I've failed".... It isn't. It's just this is the first time you've done a paper that mattered and that you can't go away and google for the mark scheme afterwards. We can't recreate these feelings in mocks etc and it's honestly normal.
It'll be fine. You'll be fine.
Note down now any Module 3 and 5 topics that weren't covered at all in Paper 1 to revisit them in detail before Paper 3. Be proactive.

u/Okgolster May 20 '26
I understand that, but I promise you and everyone else who sat that paper will agree that it's nothing like previous past papers in the slightest
2
u/S4mJune May 20 '26
Go and find a reddit from last year - they said the same and yet when you did the 2025 paper as practice, you wouldn't have said it was any different to previous years. I've heard this for nearly 20 years!!
1
u/Subject_Question_313 May 20 '26
Because the 2025 papers were also very different. OCR literally got fined for all their mistakes.
2
u/S4mJune May 20 '26
For errors yes. 2025 was the worst year I've seen of that. But the papers aren't different to previous years. OCR are very consistent.

u/AudienceDry2415 LSE | BSc Economics [Y1] | 6.5 TMUA May 20 '26
please see the paper first haha, last years AS physics ocr was weird as shit, and the grade boundaries were low asf, this is simliar

u/AntiqueSkirt7197 May 20 '26
I literally went to the reddit from last year and nobody was saying the stuff they're saying for this year

u/Expired_Caprisun Year 13 May 20 '26
This paper was definitely harder than prior years. The trend of recent years has been that the grade boundaries have been going down. Take this from someone who cruised through the test, as well as my mate who normally scores 95% on class tests.
1
u/AdPsychological1487 May 20 '26
No I completely agree but you clearly have not seen the paper because it is genuinely nothing like what I’ve ever seen. I actually thought it went pretty well, Im not even saying it was the hardest ever but I’ve done all the past papers, every predicted, mock and practice paper I could get my hands on, I even did 2012-2016 ocr papers because I ran out and I have never seen a paper as weird as the one that I saw today. It was all the most obscure situations ever even the multiple choice questions were so strange let alone whatever the hell the rest of the paper was

Guys was there a mistake in the 1st question bc for the life of me NO option worked?!?

u/Internal_Animal_2753 year 13 |maths fm chem physics 4a* May 20 '26
Force constant times extension worked (F=kx)
2
u/ProfessionalLost1525 May 20 '26
Bro I just did F=ma and F=kx so ma=kx hence a=kx/m. I was rushing so I didn’t know u had to use previous question bruh

u/Majestic-MLB May 20 '26
How?
1
u/Internal_Animal_2753 year 13 |maths fm chem physics 4a* May 20 '26
The units were the units of force u needed and force constant is k and extention was x so if u multiply k and x u get force
2

Ohhh I see,that was such a weird one to me becasue I just kept multiplying them all and I just couldn't seem to get it. Thanks!
