# January 2009 AQA Physics New Spec Practical UMS watch

1. Does anyone know how the raw 50 marks will be converted into UMS?

Thanks
2. Nope, I have got this on monday.

Any tips?

I DO NOT want to know what the questions are or anything like that.

3. I have no idea, but would like to know also.
4. All we have done, is gone through how to plot a graph :/

Not useful at all!

I do not even know what the experiment is on so I cannot even revise calculations or anything for the written exam.

(If there is calculations..)

Our teacher was able to tell us what it was going to be on.
6. So you can tell us

Ive got a feeling it will be EMF and Internal resistance..

My teacher went over that again out of the blue.

Am I close?
7. Well, Ive done 2, got the 3rd and final one in the next few weeks.

Well, it will vary between school, but I did a EMF/Internal resistance one and a weight/forces one.

HA HA! Very good!
9. It is EMF then.. Great! My least favourite topic.

Is the paper horiffic?
10. what did you guys do then?
11. is this route T or X?
12. Route T I think.
13. You cant work it out exactly yet but you can work it out roughly.
Divide your ISA percentage by 100 and times by 60. This is your UMS for the ISA.
240 - the ISA UMS gives the remaining UMS needed for an A overall. Divide by 2 and this is the UMS you need on both Unit 1 and Unit 2. Divide by 120 and this is roughly the percentage on Unit 1 & 2 for an A overall.
14. At my school ours isn't on anything to do with electricity. We have done 4 practise ones and they have all involved forces due to gravity, springs etc.

So its pretty obvious what kind of experiment its going to be.

has ur teacher given any tips?
16. There isnt really much to it. The first one I did I got an A in, and all the ones after that i dropped a mark or two for crossing out, but I wont do that in the real one.

Learn how to draw graphs properly if you cant... MAKE SURE you do repeats of every reading you take and average it. And be neat. If you dont do well something will have gone drastically wrong, it really is just like any other experiment you will have done in the past.

Hope that helps?
17. is this the ISA or practical X fing with the stopper and horizontal ruler ?
