UNOFFICIAL MARKSCHEME!~AQA GCSE Physics Unit 2 25th Janurary NEW SPEC Watch
For me to make an unofficial marks scheme, I'de need to know the questions? feel free to try and recreate the question paper.. or find a copy somewhere...
1i). Something about oil leaking from a car and what force causes the oil droplets to fall to the ground.
1ii). Points A and B with dots representing the oil droplets closely together and eventually spreading out closer to point B.
I can remember some of the other questions but not the question number for them.
i got 0.22 for the pd one-where it starts ..... will i get a mark??
i got 1.67 will i get full marks?
nd i wrote weight instead if gravity?
Apparently 1.67 is wrong and it's 1.7 however I got 1.66 and didn't round up (stupid me).
alas, it's likely a mark will be deducted for 1.67, as the question asks specifically for 2sf.
As far as i'm concerned, weight is the FORCE on an object DUE TO GRAVITY, and gravity is not the force, hence the previously mentioned N/kg unit, but i'm not certain on this
because the outwards force of fusion (created by the heat fusion produces) is matched by the inwards force of gravity, and thus, the star has reached equilibria(not expanding or collapsing).
