Centripetal force is always towards the centre

Screwed here. I can do everything, I just suck at seeing the links between equations.

I have a feeling the 6 marker could be on resonance. Its the only topic that hasnt been asked about much in past papers.

How was it?!
Do you know anyone who does a mark scheme for these kinda things, or do we kinda form our own answers for questions we can remember :biggrin:?

Section B of this paper was pretty much really nice. Section A though, ugh. I didn't have enough time for any of it, I guessed about 8 questions :frown:
The six marker was a bit of a gift :smile: I agree, there were some tricky questions towards the end of section A

I felt exactly the same. Even the flux stuff was straightforward enough and the 6 marker could have been worse. Reckon I lost 10-12 on section A though :frown:
The energy question for SHM was so vague, and such a bitch. 2 marks and 4 likes to talk about all that? You've got to be joking. Did it want kinetic and potential as a whole, or kinetic, gravitational and elastic...I went with the latter

I didn't mind section B for the most part and I think I actually understood the 6 mark question.

I found quite a few of the questions in section A tough though.

*sigh* there just isn't enough time to get everything down to the best of your abilities... I feel that 1 hour and 45 minutes is just not enough for everything I've learned about unit 4, just to guess on section A because I didn't have enough time to write my answers.

Section B, perfect. Section A, questions took too long + not enough time to complete them all perfectly.

Will somebody just tell me the time period so i can start crying, everything led on from that :frown:
Man that exam was an amazing one! managed to finish section A in exactly 35 minutes - Thought it was a pretty decent section A tbh 1/2 questions I wasn't 100% on but had some educated guesses

Section B was decent, had been very recently going over capacitor charge/discharge so happy about the 6 marker :smile:
I feel like you need 2 hours for this paper, or reduce section A to 20 questions
