Hi I could't find one for us sitting AH physics in 2014 so I thought I'd make one. So who is taking it this year and what did you get in your exam?

Has anyone got any ideas for an investigation and any links to good websites covering unit 1?

I'm taking it, got an A in the higher - pretty confident it was a band 1, but I'm too lazy to check :L

Alas, I don't have any sound ideas for the investigation yet - but I'm still holding onto the idea of cracking cold fusion in my shed :P

Figured this thread probably needed a bump, Physics is going pretty well for me atm, but going by the amount of effort the uncertainties in our learning outcome experiment thingy required, it could be about to get a bit tricky :P

Yeah I am doing AH this year too

I am looking at the viscocity of different liquids I think but not too sure.

Got an A1 at higher and doing my investigation on moment of inertia which is quite useful actually as we will soon be covering it in class.

Don't know for sure, but have you tried scholar?

Yeah I'm doing Adv. Physics this year. I've had some ideas for the investigation. So far I've been considering a little acoustical engineering by way of filters and such. However I intend to build a telsa coil if it satisfies my school's health and safety conditions and my teacher gives it the go ahead. Should be a fun year.

I want to do something related to the Mechanics unit but I'm struggling to come up with ideas.

Have a look here bro. Although this is for experiments carried out in HW labs, your school will have quite a lot of the equipment needed, but there will be some things on the list you can't do in school.

Hi, this may be a bit late but did you manage to get your SCHOLAR password sorted out yet? If not we would suggest that you ask your physics teacher or you could enquire at the school office. Any problems let us know!

My school said that they haven't sent any of our details to scholar about our courses yet because we are using a new computer system and it ****ed up

Hello! I'm doing it this year too, and I'm really enjoying it so far. Got an A2 last year.

Ah, that's a pain. Unfortunately we can't do anything until your school sends the details. If you want to message us with the name of your school (and, optionally, your name as well) then we will get in touch with them about it...

As well as Asklepios link a few posts back: http://www.thestudentroom.co.uk/show...1&postcount=11

IAmAce started last years TSR thread Advanced Higher Physics 2012-2013 : Discussion and Help Thread at http://www.thestudentroom.co.uk/show...09&postcount=1

Here's also the previous years 2011-12 link http://www.thestudentroom.co.uk/show...62&postcount=1
if anyone interested.
This thread discusses investigations, links and general tutorial problems that all you guys are repeating here this year- so it would not hurt to spend a few hours reading through these previous years threads for ideas etc.

All Highland Virtual Learning (HVLC) videos can be found on my Youtube channel link-here: http://www.youtube.com/playlist?list...I2WrVu91LAe_cm
(note- the original videos at Highland learning don't appear to be available anymore!)

trinity has good links here:http://www.hswd.co.uk/trinity/index.php?menu=0&page=150

My own site: http://physics.tomctutor.com/
has detailed notes on the AHP stuff (Excel notes etc and tutorials)

so good luck yae-all and get stuck in (its Adv. Higher) yae canna crash it Yae need ta swat hard.

Hi. I got an A band 1 in physics last year and since im going into engineering, I thought I should give AH physics a try. So far its been okay-ish but I suppose the hardest thing is just knowing what formulas to use and how to derive different equations during a question.
My investigation is the proportional relationship between magnetic flux density B and current I and I just have to do my last experiment before I get to the report and trying to do my uncertainties.

Helmholtz coils are quite accurate arrangement for producing a linear magnetic field, paraxial and central of course, the only problem is getting the central axis of the coils aligned - can be tricky. You can measure the B- field strength with a semiconductor probe (Hall Effect calibrated of course). Be careful to ensure that the probe is orientated precisely - using twist until you get maximum reading etc. The desk and clamps can affect the results- think shielding! Lots to try and write up- take lots of readings, more than one set in any run. There is also a way to measure the force produced by a wire carrying a current through the poles of an electromagnet F=Bil technique, using a weighing machine pan etc - you could maybe do both experiments.
The Helmholtz coil stuff at: link


The top-pan balance experimental method is well covered in the doc: link

Good luck, to really impress your markers best to do an Excel sheet with plots etc as explained in my web-site (mentioned in previous post).

IMPORTANT: sketch or photos of your experimental setup showing important equipment, what you are measuring, how you measured what and the calibration of your equipment - especially current meters or probes.

Try to produce a direct-proportional graph - slope!
Your graphs must show measurement errors bars.

Just ideas!

oh, thanks I've tried the current balance method and the hall probe method so far. Right now, im working on an experiment that includes a search coil connected to an oscilloscope which will measure the induced voltage across the ends of the search coil inside a slinky solenoid.

We started this year with our investigations so mine's nice and finished Just on the topic of graphs and stuff that were mentioned above, the LINEST function on EXCEL is an absolute godsend! It will calculate the exact gradient of your graph as well as the uncertainty in your gradient (saves all that pesky fannying about with quadrilaterals and what not!) among other interesting things. I believe, although you may have to ask the more experienced people above, that if you use it then you don't have to do error bars. Don't treat that as gospel though, make sure you check with someone else.
