Edexcel A-Level Physics Paper 1 (Advanced Physics I) - 9 October 2020

How is everyone feeling about this tomorrow?
I've been either scrapping As or getting just below an A in all the papers I've been doing, so I'm a bit worried that I won't get an A cos my CAG was a B, so getting anything less than an A would be pointless.

Hopefully, the grade boundaries decrease but who tf knows if they will.

Went decentlyish, idk how i did. I couldn't do the last question on the momentum of the particles and also the one with the 0.0001 ohm resistor in parallel.

that one was easy just find out voltage through resistor, as in parallel the voltage is same across both.
and then just do r=v/i.
it should give you 0.009, which is basically 0.01

Well it was only worth 2 marks I believe, and there's a chance I got the first one. How did you find the rest of the paper?

apart from one or two questions, the paper was easier.
The mcqs were really easy and i was expecting them harder.
is there any chance us two can discuss the answers.

Yeah, we can, I saw a load of people discussing AQA stuff in the general autumm megathread. Unfortunately, I havent found anyone else who sat edexcel tho apart from you.

yh so in my opinion the spider and the car track was the easiest questions.

I sat edexcel today, I found the first half a lot easier than I thought it would be, second half more difficult but defo do-able

I was bugging for part c on the spider questions, was it just Kinetic Energy = Elastic energy and plug the extension in each leg into the elastic energy formula?

only the final question was hard and that too the last part only.

Yeah the spider and car track were relatively easy questions. The only question that I had absolutely no idea what to do was the very last question with the momentum of the particle tracks. We weren't given any angles, any masses or anything so I'm a but confused as to how you were meant to do that one.

was it it do with impulse
i did force = mass x velocity found in above part ( that's why they said show) and divide by time.

I think i took a lot more time in the first half mostly due to nerves, but I think almost the entire paper was mostly doable.

I struggled on the Charge capacity question, the one where it said could the battery last for 7s

find energy using e=qv, where q = it.
and divide by max power of motor and that should give you something like 7.8s

I think I found that it would last for 39 or 40 seconds if I recall correctly. Since you had to convert the AH into C, so I multiplied by 60^2.

I think i did it a different way if I remember, but i can't remember exactly what I did, I think i remember trying to find the acceleration of the legs or something. I can't remember lmao.
