How did people find the exam? Hope it went well :smile:

went well you know the question on potential difference with a resistor and a switch I got 3 volts for both of them did anyone else get the same answer or something else?

I thought it was almost too easy ngl only one or two questions confused me but we shall see with the results 😉

Ooooo wait I got that but I was unsure if that was correct

same my friends said they got 3v and 1.5v

what about the mcq on velocity time graphs I put the curvy one I think it was d

Hmm is that the one with the biggest displacement , I put the two squares because I tried to calculate the area under the graphs for each

i put 6 and 3 volts so probably wrong, everyone get 50 for the 5 marker on spring constant, extension and force

Noo?? I got 2.8 but I didn't really have a clue how to do it so I could very well be wrong i think I did the gradient of the graph and then divided that by 0.8 I was just happy I got a whole number😭

yeah the 5 marker was 50. Many people didnt convert it into metres so few go that question wrong

thats good the 6 marker was so good what did u put?

I think it was A

I thought it was A(the one with the square and triangle on top) it couldn't be any of them with one above and below as the displacement in both directions would have cancelled out

Ohhh that does make sense

Found this paper more challenging than bio and chem, I hated the circuit questions, what happens to current and potential difference? And I got 3 and 3 V I think that's wrong though

damn I put 3v and 3v usually physics is harder in paper 1 at least

I got 1.2A, 6V and 3V and I think I seem right. At first when I glanced at that question I thought immediately that I wasn’t able to do that, but eventually I realised that this was a series circuit so I was able to do it. I put 6V because as the switch was open I thought there was no current flowing through the lamp, so I assumed that the pd for resistor equals to pd for the battery.

For the current question, I said that the current would half when the switch closes because the current flows around the whole circuit including 10 ohms instead of 5 ohms, so I would have to do 6 /10 which is 0.6 amps if switch was closed, and for the p.d of the resistor I said that it also halves because the total resistance doubles once the switch closes meaning there’s current in the lamp, and both have equal resistance, so must have equal pd. I assumed that pd of resistor = 3V and pd of lamp = 3V after the switch was closed. I think I seem right but maybe I might miss something out.
