Hi, does anyone have a list of the experiments we're expected to be able to explain for AQA physics unit 1 and 2? Since those are the biggest questions I'm slipping up on atm.

Thanks!

Unit 1:

How resistance varies with temperature
Determining the resistance of a resistor
Determining the resistivity of a material (mostly wire)
How to prove if a component is ohmic/non-ohmic

Unit 2:

Determining the Young's modulus of a material
Determining the spring constant of a material
How extension varies with load for a spring

Thats all I can think of atm, is it just experiments? Or all the 6 markers in general.

Yeah just experiments, do you know all the points we should cover for 6 marks?

Thanks a lot!

I do know all the points, but explaining it on here would be a waste. I suggest seeking the mark scheme for all the 6 mark questions and studying how you can achieve the 5-6 band and looking at the additional point section. That's how I learnt them also, doing a question and getting a teacher to mark it rather than yourself helps alot because marking yourself tends to lead yourself to a false sense of security, whereas a teacher gives you valid marks with advice. Good luck

Not an option for me unfortunately, I'm self-taught :/ I sometimes get my girlfriend to mark me though because I'm always wary that I may be being generous lol.

But thanks for the list, that'll come in handy over the next few weeks!

What other 6 markers could there be, that aren't experiments?

Photoelectric effect
Explanation of line spectra
Explanation of a certain velocity/time graph
Classification of particles
Explanation of how the photoelectric effect proves particle nature of light
Formation of stationary waves

Another experiment long answer I forgot was the determination of wavelength from double slits or diffraction. So that's using the diffraction grating equation and fringe spacing equation.
