Did anyone do this one?? How did you find it??

Couldnt even do question 1 and the momentum question was a bit tricky .

Hey,
I was just wondering how people have found this paper...I personally thought it was quite difficult...although some aspects of it were okaish such as question 2...however the majority of questions i thought were hard..
There was however quite a lot of theory questions compared to mathmatical problems which i did'nt like.....

So..how did everyone else find it?

Question 1 was nasty. The one about the mean squre spped got me. I know what root mean square speed is but i don't get why it would be different for molecules of two different gases atthe same temp.

Yeah, therewas TOO much theory. More maths and calculations would have been better...there was really little stuff on energy/work done/power...

Too much writing!!!! >.< ((The momentum ones were horrible))

The only question that was OK was the motion under gravity one.

To answer that, i put different gasses have different masses, if the temp is the same, then they will have the same KE, that means that if the mass is higher in one, the speed will be lower.

i just wrote mean square speed doesnt depend on temperature

I wrote that mean square spped depends on mass and kinetic eergy. It might get a mark.

oh wow i wrote exactly that...

i feel soo much better now knowing other people found it hard too...
my teacher told me that if many people found it hard then AQA put the grade boundaries down...

The mean sqaure is different because the molecules have the same temperature so the same KE, but if the mass is lower, the mean speeds willl be higher. That's the answer. I thought the last question of the plane question was tricky. I managed to put my answers in last 2 minutes for the vertical motion/resultant motion for the dart. What did you people put for it?

Certainly not enough mathematics and too much theory. But thats good since I revised a lot on the theory!!

the whole paper wasn't horrible, it was allright, each one of the question was easy and the whole school had the same opinion and even my teacher was saying that it was easy and the grade boundaries might be high. In my opinion they were all easy but it was a bit more theoretical than previous years, although its my first time, the test was quite easy.

Haha... i did terrible. When i added up the marks for all the questions that i actually put an answer for, i could get an E. And apparently a lot of those answers are wrong anyway. :| Haha, i'm looking forward to telling my teachers & getting my results.. everyone will be so pleased.

I thought it was rather straightforward, I'd have preferred less writing questions.

Thought it was much harder than I was expecting. Way too much theory for me, some weird questions where they seemed to pick random stuff to write questions about (eg the dartboard one, what was the point in that except to confuse people with the paragraph of text above? It just seemed to dress it all up for no reason at all ) etc. Dont think ive improved upon last time but I dont really mind too much if I dont. So a tough paper I thought.

who got an answer to the question about temperature change as 4, that one was one of the easiest

I got that, but then a few people got 0.1 or 0.01, something like that so I wasn't sure :/.

I think i also got that but i left mine as 3.9 something i can't remeber exactly i agree this was a simple question....

I got 4 exactly, and so did most of the people I talked to. What everyone get for the dart question? I got 8.something at angle of 17 degrees to the horizontal (or something similar).

for the dart question i got the first part for time 0.250 sec (3 sig fig) and then with the question about the magnitude and angle i got something like 13. summit and then my angle was 51.3 degrees because i did tan-1 10/8. since it is 10 is the opposite and 8 is the adjacent u need to use TOA.
