Had no clue what to write for that last 6 marker 💀

I wrote about wind opposing and changing v as my independant variable and measuring velocity of object as well as keeping mass constant

I spoke about adding another voltmeter in parallel to the power supply to measure internal resistance as it could lead to a systematic error (I was waffling out my arse)

I spoke about current only flowing one way so ensure ur voltmeter is connected to the right pannel

I talked about air resistance. Kept mass constant and then using the variable speed fan increase her speed. Complete waffle

We had similar approaches

Isn’t that what the diode’s for 😭

Definitely less than 200 for a*
Paper 1 - 66/110
Paper 2 -80/100
Paper 3 -49/70
195/270 A* I think so.

I just said have a switch to prevent components from heating up.

Ppl could measure 0 readings that’s y

What was the shape of your graph btw, I did an exponential and only allowed the current to be +ve so it started at the y intercept and went up from there

Omg, I forgot striking potentials exist imma lose a mark noooo
