My MC answers were:

I got very similar answers but I don't think there were so many Ds towards the beginning...

No, restoring force is min a centre of oscillation. 100% correct

The question asked for the incorrect statement?

Regardless, I'm fairly sure I spotted another incorrect statement >.<

I agree with you exactly. A* around 57, 120 UMS around 62/63.

But we'll have to find out if the AQA Gods are feeling friendly...

Mind you, people said they found PHYA2 easy last year and it was only 58/70 for 120 UMS (82%) for 120 UMS, so they may well be friendly...


I'm still shocked at how low the PHYA2 boundaries were last year.

Defo, apart from the first D, the other Ds seem very odd :/

Ooopps. Yeah, centre is right. We were thinking off different questions.

what was the last part of q1 on section b
What did people get for the radius of Venus?

8.87 = 4/3 pi * ~5400 * G * R

R ~= 5.8x10^6?

The one you're thinking of is the one where which is correct? And it was was a is 180 degrees out of phase with x

For the first one, everything was conserved wasn't it?

What was the value given for the density?

Yep. I put that one!

Sorry for confusing everyone haha. I've had a bit of a nightmare there!
Hey, I made a graph of predicted answers to the multiple choice, based on myself, and the posts here. Perspective: I am predicted an A* overall, I have gotten at least 20 on every multiple choice paper I've done, and by this data, I have at least 20/25 (Mine is the top row)

They were lower than the potato haha.

Having said that, I got 120 on PHYA1 and only 113 on PHYA2...

Something Iike 5.05x10^-3 i think. Can't remember exactIy, it feIt strange them giving us a new equation and then again on the momentum, feIt Iike i was doing something wrong even if it was just maths.

"OnIy 113" STAHP
