Physics HL

Is it possible to not learn electricity and still do reasonably well?

hmmmm52

if you've all your other sections well revised esp. modern physics then yes.....but depends what you consider reasonably well. you'l have no choice in section 1 and prob have little or no choice in section 2 either?

muffinz

whats "modern physics"? :pac:

hmmmm52

sorry should hav specified thats what our class called the section thats got einsteins photoelectric effect...e=m(c-squared), x-rays..cockroft n walton, nuclear fission/fusion...radioactivity, particle physics etc.
its generally question 10 a comes up as a part in q.12 and sometimes comes up as another full question...(like 8 or9 . . or 11)

I didnt do electricity or magnetism(except mandatory experiments and some commons short questions) and got an A1 if that's any good to you.

Cen92

I'd be hoping for at least a B.
I reckon I know the experiments pretty well and should be ok for most of section B but I'll try to avoid electricity as much as possible

I think most people are like that, tbh. I'm one of the only ones I know who likes electricity! You should be grand.

what exactly are the electricity chapters? and anyone any predictions on anything? I have left absolutely everything until the last minute!!

What are the common short questions??? Any help will do!!

electicity isnt bad in fairness.. especially now that we have all the equations in the new tables!:D just learn the definitions and ul be grand

bluemooner

true, im not doing the electricity questions either. you should however learn a few definitions for the short questions and know a few of the experiments at least. good luck anyways!!!

Cormac2791

yep, im dead in this!

Conor108

HATE electricity! I know the electricity definitions and demonstrations for Faradays & Lenz. Thats it!

I'll avoid it in Section A. If electricity defininitions come up in good old question 5 I can do them. And sure I'm grand on mechanics, waves, heat and modern:) I actually love modern physics

I genuinely can't remember. Did LC in 2008.

Maybe what is Ohms Law or something. But you can answer them with a formula normally i think. Dunno what story is now that log tables are supplied.

Don't know if I answered anything on electricity in the actual exam... was more of a mechanics or modern physics person :pac:

Cen92

Yeah I love modern physics and mechanics is pretty good. Waves and heat are ok too!

muffinz

if they ask what coulumbs law is, can u just sai Q1Q2/ etc or dya have to say the english version? coz thats like 3 lines long and my brain cant handle that many physics words in one go

whats the demonstrations for faradays and for lenz? holy sh*t im ****ed the only thing i know are my definitions

Theres a coil of wire connected to the galvonometer and you move a magnet in towards it. Thats Faradays. Lenz's law is when you have an alluminium ring suspended from a wire, move a strong magnet away from it and the magnet follows it. Move the magnet closer, the ring movies away.

Muffinz, I'd imagine that while the format of the papers won't change to account for the tables, The marking scheme will

I'm thoroughly f.u.c.ked. Its 10.30 and I still have absoltuely LOADS to do in physics anyone else absolutely in intellectual shambles?

i cant even remember ever doin those before.. right im off to hit the books!!

almostnever

I know one experiment.

I can attempt the short questions.

I can give the option a go.

In short, I am SCREWED.
