Physics - Aftermath

Cipango

Couldn't have been happier with it!

Experiments were a doddle and question five was probably the easiest ever!


Question 10 was tough enough but there were plenty of decent alternatives to avoid it!

Was dreading physics the most but now....weight off my shoulders!

was an overall nice paper i thought! 10 was a bit tough (think messed up iii) but overall think it couldnt have gone better!

I think I must be a bit weird because I thought overall it wasn't the best of papers, but I thought the question 10 could have been a lot worse hahaha. Either way, DELIGHTED to have my options started, roll on Thursday

It was alright. I am happy with it though. Most of the questions were fine.

Only issue was some of the calculations - I think I messed up a few. I got over 4 millions meters for the lenght of the coil in the Hairdryer question!
Is the marking scheme for the calculations the same as in Maths - with blunders, attempt marks and such?

Very happy though!

I suppose it was just everything I had learned so to me it was easy rather than an easy paper in general

I was fairly satisfied with it. I only got one part wrong which I know of, and it was the chemical effect of current, which I couldn't remember for my life.

Otherwise, I found all other questions a doddle. Question 10 wasn't bad either. Muon and Kaon are the only mesons like.

Ok so in the last few seconds i noticed that one of my graph papers was ripped!! you know the whole that you put the thread through, that had a tear so the thread would just slip out through it!! i sealed my booklet even though the examiner told me not to for some reason, do u reckon it will be ok? i have my name on it, but im terrified.. plus its the sin i sin r graph, which is worth a good few marks that i need

I'd say so! Like I slipped my Irish aural into the booklet without the thread

yup!
didnt matter i had no idea what the feck they were on about!

probably the easiest physics exam paper I''ve ever seen. Particle physics question was harder than most years though.

Yet again, you can see that they're tryin to get rid of predicting, everyone was CERTAIN joules law was coming up!!!

I thought the experiments were predictable. I only covered about 10 and 4 of those came up. I mean if you're only doing 4 you're obviously taking a huge risk.

well me and you go to a poor school that can't afford the graphing calculator yoke or whatever it was

i'm assuming your used to using a ticker timer and ticker tape... an absouulte disgrace that they put that up on the paper... not every school uses this set up or whatever it was...

i think this is what it is anyways... according to my teacher that question isn't allowed because their not supposed to be allowed to tell us what way to do any experiment because different schools do it different ways...

like our school doens't even own one of them yokes so how in the name of god was i supopsed to know how to do that question... which threw q12 out the window in my case as it turned out because i was only able to do 1 of the other parts out fully...

can't believe they were naive enough to put this up thinking that people wouldn't complain... then again - suppose the more controversial it is the better

Am I the only one here that had a problem with that paper? I thought it was awful!

I couldn't think of a second reason for not measuring below 30 degrees,
I didn't know why the F=ma wouldn't go through the origin,
I found it hard to describe the red shift,
I'm sure my explanation of the x-ray is wrong,
Question 10a was a disaster and
I had to guess for most of question 11.

Overall, I thought it was more difficult than other years, and I'm starting to worry about the good responses here now.

ps. Also really disappointed about the lack of circular motion, SHM, density and other mechanics

i agree with these 2 points as well... 2 reasons greater percentage error is all i can possibly think of...

also - if f=ma didn't go through the origin then obviously their doing something wrong how are we supposed to know what they did wrong.. for all we know they set it up wrong... if it didn't work then that means either the experiment doesn't work or they did it wrong by taking innacurate measurements or by actually forgetting to do something...

that's just way way way to vague to be fair in fairnes... like if it doesn't pass through the origin your suppsoed to pick your best straight line sur...

like what's the odds of it being a dead straight line through every point but not passing through the origin as well...... their either to incompentent to put their best straight line through the origin or they did it wrong... i can't see any other reason why it wouldn't work tbh

Did anyone else notice that Q11 wan't even in the book!Never in my life have I done a question on that!!Radio waves?? And Q6 what an absolute bitch! Like I got an A1 in the mock and I thought that was a horrible section B, A was grand, Bwas unfair! Such a boy-orientated paper too

Hey John, did you get 3.51kg for the mass in question 1?

Realistically, it seemed a bit heavy to me, but I had double checked my work...

also the answer was in the passage if you'd bothered to jsut take 2 secs to read it :rolleyes::rolleyes:

sars are measured in kg per watt.... radio waves are converted to heat... blah blah

i didnt't do the question but i was looking at it because i had time over and i seen that question and it irked me the way it was phrased is all

what a stupid comment!
eh i am a girl and it was in NO WAY boy orientated?
and sorry to tell you sweetheart nothing about physics is boy orientated?

Considering how s**t I am at Physics and how I got 32 in the mocks, I'm happy enough. I'll take a C and run.:D

i'm also gonna take a dig now by saying how she got an "A" in her mocks...

luv as much as you may hate to hear it.. an A in the mocks means ntohing if you get lost altogether if you have to stop and think for a second like we did today... Q6 was hard.. yes do anoteher question.. surely an A student would know enough about a different topic to get away from the hardest question on the paper... Q11 like i said before had every answer spelled out in front of you...

todays paper wasn't boy orientated... how was it possibly... if you want to say boys are better at numbers or something... then cont up how many calculations did we have today... exactly - todays paper had a wee bit more understanding involved and you couldn't cope...

proving your not an A student in physics... i know it sounds harsh but when you try to brag about an A in the mocks and then cry that you couldn't do it today what do you expect...

Leavenotrace

I thought section A was grand also a bit put off by two reasons for 30 degrees i just said that it would make the angle of refraction much harder to measure accurately and also percentage error, kind of the same thing but hey :P

Also for the electricity experiment as to why oil and not water, did anyone else say that oil had a higher specific heat capacity and so heated the thermistor more gradually, to be fair i was bluffing that bit of the q

I thought section b was ok except for Q6 and Q10

and just on a side not papers cant be boy/girl orientated! Also how can you even say its a boy orientated paper when clearly theres a whole question about a hairdryer??

...Maybe a bit too far? :S


Re: Leavenotrace
I think water would cause bubbles to form on the thermistor when its heated, so that would lead to inaccuracies.

im sorry but yes you are completely right!!! if sh considers maths an electricity boy orientated... i cant even begin to complain about how much she has just offended alot of female physicists.
the mocks mean jack all with grades , if anything doing bad in them makes you work harder, or els some people like you get complacent.... and assume your a will be handed to you.her comment actually has seriously pissed me off!

I'm pretty sure that oil is used because it has a lower heat capacity then water so that an accurate temp can be found immediately.
That's what i said.
Complete opposite really

gycerol is an even conductor of heat so the temp of the gycerol is equal to the temp of the thermistor...
water isn't an even conductor of heat so the heat of the water is different at different spots so we can't assume the temp of water is the same as temp of thermistor...

gycerol is the oil...

Pheima

Im sorry if it offended you,it was just my view. I really didn't think there was a need for that outburst. Yes I know I found Q6 hard but I did do another 2 questions so I was just saying I couldn't find 11 in the book, but ok I do accept I was wrong. I work really hard for physics and I deserved my a so I would appreciate if you didn't try to slate me as much just to make yourself feel better. Iam not complacent I was just saying as I good student of physics I found the paper hard

ehm hun it is not making me feel any better saying that to you , just irritates me when physics is the career i want and girls like you come out with crap like that.
and thank you for admitting that
*all good*

Yeah me too:)

I always found electricity kinda tough(in parts!) and I think its great that you like it:) honestly,Iam sorry for dividing physics to male and female, after all I consider myself to be a bit of Boland:P

Darn, I have all that in the back of my head. I ended up just writing: "oil is a better conductor of heat than water" ..... "FACEPALM".

so "it ensures good thermal contact" is wrong then, I suppose? I was thinking of some heat experiment I think.
