Physics HL 2010 Predictions?

JellyBeans92 · 11-06-2010 8:11pm #1

Hi, I was just wondering what people think will be coming up on the Physics HL on Monday week?

I'm hoping to not have to answer the Electricity and did the Particle Physics Option?

Any idea's on the best experiments and topics to 'focus' on?

I'm hoping for the harmonic/'column of air' Experiment with the
Lamda = 4(L + .3d) formula.

Conor108 · 11-06-2010 8:14pm

Yeah thats nice a experiment. Feeling quite confident for physics

Plan to avoid electricity like the plague though;)

I've heard Boyle's Law & Refractive Index

JellyBeans92 · 11-06-2010 8:17pm

Yeah, I heard these too.

Really have NO IDEA for the section 2 of the paper

Think Vectors and Scalars is kinda due up for Mechanics, but am so screwed for this exam its rediculous

Conor108 · 11-06-2010 8:21pm

Well actually if electricity DEFINITIONS come up in q5 on section B, thats fine. But electricity questions no way can I do them

11-06-2010 8:22pm

It's very difficult to predict Physics tbh. There are obviously some topics that come up often, like circular motion in Q6. Learn all the experiments though!

Conor108 · 11-06-2010 8:24pm

Yeah don't think they change the format of the paper to account for the fact we now have the tables until 2011 so we are seriously lucky this year:)

You can say that again - Considering I was one of the people to do mine last year, it's a bit of a joke you're being handed everything on silver platter.

It may be difficult to predict, but you've about half the workload now as we did last year, so...

dannye92 · 11-06-2010 8:50pm

heard Joules law is coming up aswell?

Cipango · 11-06-2010 10:18pm

Also the experiment on newtons second law is due.

i'd put money on that not coming up. if it does i think it will be asked with another question, maybe with conservation of momentum or something

muffinz · 11-06-2010 10:29pm

ok so for physics for the past 2 years i just sat there doodling on my page... now i am f*cked to say the least. I swear those new log tables are a blessing from jesus!! i have no idea what to do.. i have revised lenses and refraction etc but lord what do i do someone help

Liveit · 11-06-2010 10:52pm

Im either going to do very good or very bad

corolla 1991 · 11-06-2010 11:09pm

This must be the hardest exam on the leaving cert after honours maths!...anyone agree?

Try Applied Maths. Or History.

ciano1 · 11-06-2010 11:22pm

We didnt even finish the course... Tried to learn the last 3 chapters myself but just cannot get my head around them

PARARORY · 11-06-2010 11:23pm

I heard Boland might come up as question 4 as a last minute addition by the SEC after what happened on Thursday

I literally just LOL'd at this.. just as I nearly did when I opened the paper to see she stood half the country up on thursday, the SEC curveball was a totally beaut!

**Timbuk2** · 11-06-2010 11:28pm

I hope the layout isn't changed due to the log tables. I noticed no difference in maths today, but that really isn't a guide. The only help that the new tables were in maths is the newton raphson method. The rest was all there previously.

I really can't see how we can be examined at the same standard as previous years as we have it so much easier. I hope it won't be marked harder.

I can really see a lot more derivations coming up due to the new tables.

derivations of what, like the Rt= R1 + R2... etc?

Hello again Timbuk2, on maths also the sequences and series formulas were needed, and they were never in the old tables, I can never remember them so they came in handy.

Also in reference to the sequences and series, today you needed to use the one (only one i think) formula that isn't in the new tables as well (Sn of a G-series where R>1). I think they might do this on the physics now, make use use the handful of formulas that aren't included in the tables to catch people out.........

I heard they're leaving out the honours option...?

Wouldn't that just defeat the point of this distinction between HL and OL.. Sounds like waffle.

Relax, it's just what I heard here on Boards.

muffinz · 13-06-2010 5:03pm

anyone know anything? im ****ed for this, but i have from noon thursday till monday to study... im learning definitions such as lenz' law and then relying HEAVILY on the log books...

Loucol · 13-06-2010 6:35pm

Do you think the new log tables will affect our paper? I'm really nervous about it, or can they just change it like that?

Blerdiii · 13-06-2010 6:59pm

apparently my physics teacher told us the paper was set prior to the new log tables. he said they cant change the paper and it was one of the first to be set so the new log tables have not affected the paper. if they change the format they have to make sample papers available!
i share everyones pain with electricity

but the problem with physics is every part of the course is examined in someway or another so electricity can come into other questions

the tables came out last July so the exam was defo set after the tables had been out

http://www.examinations.ie/schools/S_60_09_Information_re_Formulae_and_Booklet_Tables.pdf

Please read the bottom of page 5 (I think?)

This basically implies that they can't change the way the paper is asked as such, because technically when we started Physics in Sept 2008 we were told that we had to learn all those formulas and would be awarded marks for them?

So by not giving us these marks would be changing the paper, which they're apparently not allowed to do to us this year, so we get the best of both:
1/ Handed the Formulas
2/ Handed marks for knowing the Formulas

Hope this helps?

i hope for a lot of electicity !:cool::cool:

:cool::cool::cool:

...Because im going to repeat next year so it won't be there

This means that, in 2010 only, candidates will have access to the information concerned in both the new Formulae and Tables booklet and on the examination paper

love that part

thanks

TurkishNeon · 17-06-2010 8:56pm

We are so lucky!!
Do you think they will have lots of derivations on the exam to compensate?
Or make the exam harder?
That news has actually made my day, MARKS FOR FORMULAE that are in the log tables

Is there any formulae not in the book?

Id LOVE lots of derivation! Theyre so easy!

Jako8 · 17-06-2010 10:59pm

Try your best to learn all the experiments very very well. This will make you gain an easy 110 - 120 marks in Section A.

Section B is hard to predict but the option question is guaranteed to come up so make sure you know that too.

muffinz · 17-06-2010 11:31pm

I remember in the mocks some question that i had never covered before, but i just found the formula in the log book, wrote it down and got 9 freakin marks, awesome or what!!:pac:
if i had to do the leaving cert without these log books, I'd be in the bottom of the Liffey right now.

LoL, I'd the same on a mock question about Einstien's Photoelectric Effect of something.. I'd probably fail without these log books.

ddef · 18-06-2010 12:54am

Im putting all my money on the predictions and if they do an Eavan Boland on this paper im screwed

It's funny how from now on we're all going to refer to getting caught on predictions as an "Eavan Boland"

I'd go with what most people seem to be saying and look over the experiments..

Then I would suggest if you're doing option 1, look over nuclear physics and it, because you prob will get a good 2 questions at least out of that.

Some of the basic mechanics you can learn by going back over the experiments anyway

No cause its easy if you understand it, hard if you don't. English is hard for everyone, the stress of it. Physics is quite relaxed, 3 hours and not much to write. Honours maths is easier than physics for me tbh

Ah you don't need to learn all experiments VERY well. The q's they ask in section A are usually sources of error and precautions. Parallax and percentage error work marvelously

and the graphs are usually grand if you label your axes right.

I know.. We were just starting the Nuclear fission/Fusion chapter on the day we graduated. We were just left hanging!

In the weeks after graduation I tried to understand the last few chapters but just couldnt make head or tails of it.

Thats one less possible question I can do on the paper on Monday

muffinz · 18-06-2010 3:23pm

so what experiments do u think will come up? i hope refractive index comes up, easy peasy, and its due up apparently

but for the section 2.... ugh i dont know where to begin. im learning my definitions as they usually come up in Q5, but hm.... maybe ill try and learn the derivations?

I don't think the option is guaranteed. I mean, it will probably be there but they don't HAVE to put it on..

muffinz · 18-06-2010 3:36pm

im thinking of dropping to pass... what are the ordinary papers like?any easier?

If you have exam papers they will contain both pass and honours, for physics. Pass physics isn't a whole lot easier. You need to know much the same things, but in less detail and the questions are easier. For example, you don't need to do vectors, derivations and the option.

ciano1 · 18-06-2010 3:51pm

Good Experiment tips from another poster in another thread..

I know people are only sticking to 4 experiments that are predicted...but to me this is madness! If you ONLY stick to what is likely you may find urself schnookered!!!

For the expreiments the top 4 to come are reportedly:
Boyles Law
Acceleration is proportional to force
Vaporisation of Water
Joules Law
But rather than saying all 24 (or 25) Expts should be learned im only learning 13:
Focal Length of Concave Mirror
Snells Law
Acceleration is Proportional to Force
Conservation of Momentum
Boyles Law
Co-planar Forces
Simple Pendulum
Calibration of Thermometer
Specific Heat Capacity of Water
Vaporisation of Water
Speed of sound in Air
Joules Law
Resistance of a thermometer with temperature

Plus for Section B

Know definitions and derivations (will get you half marks in some questions and nearly full marks in Q5)

Electricity

Light (Tipped)

Heat (Tipped)

and the rest is repetitive.

Theres a great site to get some resources thephysicsteacher.ie

This man turned my grades around! He has great notes and theyre free. Especially like the short question notes!

How do ya study for physics?
Most fomulas are given, I know most of the definitions and am gonna study the above experiments.
What else is there to know apart from devivations?

thats disgraceful , we have done the course 3 times, physics techers can be so ridiculous

muffinz · 18-06-2010 4:23pm

ok so what derivations do we have to know?

and a quick question on the doppler effect, ive never really got it.
if there is a person at A and a person at B, and the items moving towards A, does that mean they will hear the noise more often but it will be less loud? and B will be less often but louder? or am i totally wrong?D:

Hurlyburlycurly · 18-06-2010 5:07pm

If the object is moving towards A, The perfon at a will hear the object at a higher frequency! The person at B will hear it at a lower frequency!
