AQA Physics PHYA5 - 28th June 2016 [Exam Discussion Thread]

Yeah I'm in the same boat. Self teaching and I can't find any good resources

The part I dread most is the COP stuff, it's very hit and miss at the moment for me

Same here, all of the engine stuff I don't get any of it. I can do rotational because I've done M2 and M3 luckily

What resources are you using? I'm just using past papers and the specification you got any that you can link to me please?

5C applied physics is so hard

umm guys, are the kinetic theory assumptions the same as the ideal gas assumptions?

Do you guyz know all the definitions of keywords in nuclear and astro physics?

There's no such thing as ideal gas assumptions only kinetic theory assumptions

There most definitely are ideal gas assumptions. By definition there must be because no gas is ideal and so you have to assume a few things to then treat a gas as ideal. An example being there are no interactions between each gas molecule which is obviously far from the truth as there are van de waals forces between them and if you drop the assumption, you end up with the van der waals corrected ideal gas equation which is called the van der waals equation of state. You could argue that there are crossovers between kinetic theory assumptions and ideal gas assumptions which is true.

But in effect they are the same since they have the same assumptions right ?

Can someone please help with qs 4c on section A ? How do we know that more time would be spent below 25 degrees?!
Thanks

lol with the applied physics part in section B I think I prefer section A

Someone answer me please

Love your name lmao

I haven't even revised yet. I'll get back to you if I find something cool. I'll likely do old spec questions for applied and study mark schemes

Yes actually try this

anyone know why Ek = eV ??
