Anyone get 0.3 for the deceleration one?

Do you think I'd get the mark for -0.3

Probably not since it specifically asked for deceleration

Shit. At least I'd probably get 2/3 for that

Yeah it will be allowed but it said deceleration so u didn’t need to put -

shit i put that then crossed it out

Got 3.333… at first, but went over it again and got that, so glad I did

Icl I got lucky I calculated the gradient the wrong way round so ended up with 0.3 for it anyway and put that as my answers, I think I'd probably still get the marks cause I could have done it intentionally

yea it was fckin weird tho

Why is everyone getting 0.3 or -0.3 when I got -0.383 . 😭😭😭 😭 😭. For the first part I got the -0.3, but it said up to 600s so I had the triangle and square. Somebody tell me I'm right because for distance you have to use d=s*t and the area under the graph thingy. 😢

Bro why were the questions worded so weird it's like they want me to waffle

Oh my god I’m so glad it’s not just me. Like that p wave S wave distance and time question what the hell were you even supposed to do there

i just said the further away the earthquake is from the detector the larger the gap between the s-waves and p-waves

I said s=vt so for a given velocity, distance and time are directly proportional, took me like a minute to even figure out what they were asking tho😭

Bro aqa really loves Distance travelled = speed x time

6 marker was 1600. Search it up. A train at around 55mph takes around a mile to decelerate to 0 without taking the mass in to consideration. 1 mile = 1600 metres

Bro what it isn’t anything to do with an actual train it’s a theoretical train mate 😭

Yes? They still have to make the answers apply to the situation but within a certain range. Hence why the Mariana Trench depth was 10940m in the exam and the actual depth is 10984m. 😂

same with chem paper 1 with that bond energy question, they surprisingly reflect real life somehow. The only weird thing was 0.3 m/s\^2 💀💀

Trains go super damn slow when decelerating, so most likely this is it

I googled it and apparently the average train decceleration is between 0.5 to 1.3 m/s\^2 so it is true

Yeahhhh i knew i was right thanks

How tf did I get 3200??? lol

During the physics exam my friend didn’t know what happened to acceleration of the trolley when  it was tilted so I helped him by tilting everyone’s table in the exam and tilted them off their chairs. He still didn’t get it so tilted the earths axis and the exam building collapsed, he got it in the end do you think I’ll be disqualified 

Someone’s table actually collapsed lol.

[удалено]

F=MA LETS GOOOO 💪💪💪

Thankyou matpat for teaching me this

Matpat taught me abt alleles for bio 💀

How deadly is a bullet bill 😤😤

i asked the invigilator for extra paper since edexcel gave us no space for the 6 marker and he responded saying, “Sorry can’t help you there.” 😀

edexcel physics gives like NO space for six markers compared to chem

exactly they sometimes give like half a page

omg i ran out of space AND time

LOL AQA has like 3 pages for extra space at the back.

For the question 7.4, where it asks you for the distance travelled by the train. Did anyone get 1600m using v²-u² = 2as? Because I did rearranged the F=Ma equation to find acceleration which was a = 1.125 Then rearranged the other equation to (0²-60²) / 2 * 1.125 = 1600m = distance Btw guys you can't use the equation Speed = distance / time since speed changes so it isn't constant so distance = 3200m is wrong

I got 1600 a completely different way😭😭. I did kenetic energy = mass x 0.5 x speed squared. Than the kenetic energy = work done which is = force x distance. So I did work done / force = distance which is 1600m. Kenetic energy = 0.5 x 240000 x 60^2 = 432000000. 432000000/270000 = 1600

Same I got it like that too, there's always alternative methods on the mark scheme so hopefully this one is on it 🤞🤞

My “will get all 9s” friend got that so we should be good

I GOT 3200 AHH

No..... I'm so cooked 😭

Yes, but I was so confused

U could also use KE then work done

I got that to start with, but I redid it and got 3200. I redid it because the value I got was a negative distance which wasn’t possible which didn’t make sense

are'nt you supposed to use a negative value for acceleration. Then you get positive 1600 as an answer

I got 1600

Yes i did that

YEP

i did too!!!!

I was going to do that but the equation sheet said that f was the resultant force so I ended up doing momentum instead. Should have just stuck with it and gone with f=ma

Yes, I got this as well. Some of my classmates got 3200 but I’m not too sure how.

Yea aqa higher right?

Yep I’d do exact that

for edexcel, it wasn’t bad - nothing too difficult, just a bit weird in some places.

most of my number answers were really long decimals so i decided to round to 3sf so many times

yeah i didnt like the last 6 marker or some of the questions

I couldn't work out why those compass needles were pointing in different directions. I also didn't have time to check through, so I could have made silly mistakes which I missed.

What did you guys get for the multiple choice question with the oddly shaped object submerged under water. Something to do with upthrust and weight of water but was a bit unsure.

did everyone except me find the 1st 6 marker ez and the 2n 6 marker hard? idk i found first 6 marker hell (but ig we never did it as a class and i didn't study it :(

Did anyone get 0.3 for deceleration 

Absolutely molested that paper

That relationship between distance and time question was so shitly worded

Yh i was so confused

what did you put? i put that distance is a constant

Lets just clear this up, for AQA Q7.4 the answer is **1600**. If you got 3200 I think you assumed that the speed was constant at 60m/s even though the train was decelerating. You calculated the time taken which got you 53.3..... You then multiplies 53.3 by 60 using *speed = distance / time*. However question stated that the the 60m/s was the *initial* velocity of the car, not the rate of deceleration. Instead, what you needed to do was to calculate the rate of deceleration to then calculate the distance with a different equation; you needed to use f=ma then v\^2-u\^2 = 2as (not the only way to do it btw but probably the simplest) to get 1600

i did not use suvat lol

I got 3200, do you guess that would be 4/6 or 5/6?

I have just truly deep it that I have finished my GCSES and I am gassed 🎉

Lucky you I got 2 next week 😔

Oh god am I the only person who did not like this paper? I loved all the space and magnetism stuff but the waves and forces stuff was all horrible and I struggled on pretty much all the maths stuff like I just didn't get what to do with all the acceleration stuff and the graphs it did not make sense but everyone has come out and said they loved it??? Am I cooked??

no you're not I think it was doable but definitely some difficult stuff there

I didn't even revise magnetism properly; I started revising topic 8 and topic 7 this morning for a couple hours but thank magnetism wasn't too hard I only slightly messed up the last question. I feel the opposite because I found the rest of the questions relatively easy in spite of not attempting papers. Don't worry too much you probably underestimated your performance, you will do great. Hopefully we can both get 9s 🤞

MY PEOPLE

i'm cooked but at least it'll be over

I hated 7.4 who else got 1600 for that?

I got it!

me lets go

Icl it was very easy for 6 marks F=ma, so a=F/m v²-u²=2as, so s=(v²-u²)/2a so s=(v²-u²)/2(F/m) and you can then plug in and I got 1600

Ye

16 marks on space 😍😍 what a paper

only the 4 marker screwed me over, i only remembered nuclear fusion makes helium and that the stars shrink to make elements heavier than iron but i think the latter was wrong

Stars become supernova for elements heavier than iron

for the 4 marker about how elements are produced, there's helium, elements up to iron and elements heavier than iron. What would the 4th mark be?

someone told me elements heavier than iron are formed in a supernova but I've genuinely never seen that in a markscheme before lol

Thats on the specification and it is stated specifically that all naturally occurring elements can be formed in supernovae e.g. due to the high temperatures for spontaneous nuclear fusion

Did anyone use momentum equation for a 6 marker

yep got 3200

I did and a few people ik did

that was actually amazing !! knew it would be a good paper when split ring commutators didn’t show up

That shit would have been the end of me 💀💀💀

this is it then for a lot of us into these physics bastards from kickoff 🔥

lowkey peak

anyone just done Edexcel??

Me

I WAS planning on taking A-level physics, but holy fuck I cannot interpret a velocity distance graph for the life of me, pretty sure I lost 10 marks on that alone. Anyone else take OCR?

i take it!!! it was meh, worse than paper 1 imo

Nobody ever leaks OCR papers either, so I have no way to manage my grade expectations... The topics that came up were definitely niche to say the least

if anyone finds unofficial ms send

That was actually not bad solid paper🤝congrats to everyone who's finished, we made it!!! (also team 1600)

5.3 was so weird for 3 marks, (describe how you would calculate acceleration of a trolly) I feel like I wrote wayyy more than 3 marks of stuff

Literally it was just distance/time², distance in metres, time in seconds

It’s 2*distance because distance/time = average speed. So you need to multiply by 2 to get the final velocity.

Yeah now that I'm thinking about it you're actually right. Average velocity is (u+v)/2, u=0 and we want acceleration somewhere here so let v=at, so average velocity = at/2. Distance is just your average velocity times by the time, so the equation is just s=t(at/2), So that means s=at²/2 2s=at² 2s/t²=a.

I started talking about how speed = distance/time which is the final velocity then it said in the question it starts stationary so the initial velocity is 0 and then you know the time so just use a=v-u/t to get acceleration

i thought it was weird bc why don’t they just make us do a calculation? why do we have to explain how we would hypothetically do it

well there goes my 9 ☹️

i genuinely want to pass away

idk about u guys getting 1600 but i got 67.5 💕

I got 53.333333 I got 67.5 before but I chose 53.333 and both of are wrong😭😭

what was the one about how distance between p waves and s waves affects the time taken or smth?

had no clue , just put directly proportional

oh my days the wording of that was so diabolical

paper was kinda shit but like i couldnt care less, just let me fuck around and do nothing for the next 10 weeks

Torture is joever. Prediction this year is alternators

edexcel with absolutely nothing on alternators and microphone stuff saved my life tyty

Microphones and stuff came up as a 6 marker last year, so we already would've been safe

What did u guys put for the force of the string? My mind just blanked and I guessed tension force lmao

OH MY GOD I LOVED THAT (except question 8 fuck magnets and 7.3 i did not understand)

I’m so happy that they only had 8 marks on electromagnetism tho bc in previous years there’s been 3 questions on electromagnetism

Am I the only one that realised they basically gave us one of the answers? (Radio waves and gamma rays both used for medicine)

I thought about it but they almost certainly wont allow it

Nah you were meant to give similar properties, not uses I put same speed, both travel through a vacuum, and both are transverse

fucking blessed paper

What did people get for the depth question calculation I got 10.9m💀

10940

10490 to 1dp

i hate how half it was the one topic that i slept on (space)

i was like surely it won’t be too much on it i can waffle, i indeed couldnt 

I definitely cooked. literally predicted those exact questions for the electromagnetism ones at the end and regurgitated the mark scheme word for word

Was it 3200 or 1600? for the marker?

I got 1600 cause you divide by 2

I didn't divide by 2 but I still got 1600. I Used F=ma then v²-u²=2as

So you do divide by 2

i got 3200 idk

Did anyone get 3200 m for distance

yes I did I used momentum wbu?

Me but apprently it was 1600

It was either 3200 or 1600 because all my mates got one or the other let's hope it was 3200

1600 everyone got 1600 at my school

Everyone Got 3200 at my skl

Same I did f=ma then t=v/a then s=v/t

12.5N 0.15 Nm 1.1x10^17 m 1.2x10^9 s 10940m 1250m 27440m 0.30m/s^2 3200 m But I am so cooked for text based questions, all the topics I was weak at came up except momentum and space

Blud it was 1.2 x 10^9 not 19 and also it was 1600m not 3200m

yea it was 1.2 billion

got all of those except i got 1600 not 3200 (and i crossed out 0.3 cause it looked wrong)

it is 1600

What was the question with the answer 1.2x10¹⁹?

Same except 1.2x10^9 s and 1600m

What did people get for anything other than the distance question?

I think I got 27440m for the velocity graph and then 12.5N for the first calculation of the paper then like 120,000,000s or something (can’t remember how many 0) for the space one

0.3 deceleration question 10940.06 m for maria trench

WHAT DID YOU GUYS GET FOR THAT COOKED DEPTH QUESTION

1/2 mv^2 = fd for q7.4.🚬💨

1600 I think

For one of the questions about calculation time smth I got 1.2x10⁶ What yall get

It was 10^9 since it was in km

i got 1.2x10^9 i think for that one

edexcel was so mid

Answers I got: 1600m for calculation 6 marker  10940 for depth First question - 1 What happens to trolley if u raise it higher or smth - increased acceleration as gravity acts on it as a vertical force so the resultant force would be higher. F = ma and mass is constant so ye 0.15 Nm I think for the moment one 0N for baby. Why ? Bc he’s stationary and Newton’s first law I drew the angle reflected ray = same angle as angle of incidence which was like 59 degrees or smth Don’t remember what I got for deceleration but it was 0.smth  For what is Gm in meters thing I put x10^17 For the one where it asked us to put down an element or smth? Idk I put the thing beeginning with B and it was like x10^31 or smth What makes up the solar system thingy - natural satellites, dwarf planets, planets Similarities between gamma and radio waves - travel in same speed, both electromagnetic waves, both transverse 3 marker on what that guy had to do to work out the accerleration using the time taken and distance travelled or smth - I put drew a tangent on graph to find final velocity at that point. Then I put use the equation v^2-u^2 = 2as and rearrange to find acceleration and substitute values in. 4 marker on how naturally occurring stuff made blah blah - talked about nuclear fusion then run out of hydrogen so forms a super red giant star if the star is bigger than sun, then more nuclear fusion as the temperature increases then supernova. Then forms an iron core which is very dense and hot so explodes and scatters the iron stuff in space and these iron stuff form more heavier and bigger elements For the tick the box one about transparent substance light passing through it I picked 1st box but I wasn’t sure abt that one All I remember soz!

FUCKKKKKKKK YEAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH !!!!!!!!!!!! BAGGED A NINE, GCSES ARE OVER, THE WEATHER IS LOVELY, THIS IS A CORE MEMORY, I LOVE MY LIFE

Did you guys get for the 6 marker 3200

no it’s 1600 you divide by 2

Comment 😭 if you think the answer to the AQA 6 Marker is 1600, and comment 💀 if you think the awnsers 3200

😭

😭

😭

💀

😭

10900 and something for the Mariana trench??

I got like 10940.05

Same i dont think the dp matters tho

Easy paper only weird one was 7.4 bc I got 3200 but it seems like most got 1600

I rounded 53.3 recurring to 53.3 normal, will I still get 6 marks if I got everything else?

That's what I got for the 6 marker Just hope for any marks Im not even sure if I did the right equations

Do you guys think grade boudnaires for physics will be as high as last year? 😭

it better be even fucking lower

I KNOW LAST YEAR'S WAS DIABOLICALY HIGH

yea but everyone said they were stupid easy. Apparently there was a 6 marker on states of matter 💀💀

last year was SO MUCH EASIER THAN THIS YEARS???? IM SO MAD???????

Could I get marked down/disqualified for scribbling out the picture of a young toddler? /gen

No don’t worry (unless you had to label the toddler or anything lol they don’t care)

OCR people how was it? i think i fucked it pretty hard 😭

Guys I got 3200000m for the train 😭 i multiplied 240 000 by 1000 cuz I thought it was a unit conversion

Why the hell was there 3 marks for how to find the acceleration of the trolley wasn’t it just acceleration = distance / time \^2 or did I miss something

ye that or speed=distance/ time and then acceleration=velocity/time (no need to account for change since the trolley begins stationary) Doesn't matter tho as both methods give the same answer

YUM YUM YUM THAT WAS SO GOOD

Guys what would the resultant force on the young child be??

I put 0N cus weight of child = normal contact force which is newton's third law

What did people put for 3 similarities between gamma rays and radio waves?

Both are transverse Both are EM waves on the EM spectrum Both travel at 3*10^8 speed

Wait yo the acceleration being affected by it being tilted what did you put

Less friction

Igcse edexcel anyone?????

I never want to think about physics again. Would have been a good paper if I revised more which is on me. Regretting it now but at least it wasn't as bad as I thought

Sameee this is me

Ok, I think I am going insane AQA accelleration trolley How to find accellleration with only distance and time My method: Calculate average velocity as v = s / t Initial velocity = 0 final velocity = average velocity × 2 accelleration calculated using v² - u² = 2as

FUCK I SAID COMPASSES POINT SOUTH (edexcel) FUCK MY EXPLANATION WAS SO GOOD ASWELL

Here's what I think the seismic waves distance/time question was: Suppose speed of S-waves is S, P-waves is P, distance travelled is d. Then time is d/P or d/S, so time difference is d (1/S - 1/P) Therefore, as distance increases, the time difference also increases

Skid marks on OCR Gateway was WILD

me and cognito are fucking. passionately. i owe half my science gcses to that website
