AQA AS Physics Unit 2 (PHYA2) June 9th 2016 Resit paper

this is a quote from the revision guide referring to a book on a table "this looks like newtons third law but it is not. Because both forces are acting on the book, and they're not of the same type. This is two separate interactions. The forces are equal and opposite, resulting in zero acceleration, so this is showing newton's 1st law" In other words it was not obeying newtons third law

pics if u can

Oh yeah that is true. Does that answer to the question on the paper regarding why Newton's third law is not obeyed is probably 'The two forces are not of the same type.' ? I put not the same magnitude which is probably wrong then.

ahh man, I think I might have done the same. Do you remeber what you put for the last question on that page? The one that said why the forces acting on the aircraft wasnt a pair of forces.

Q1 - Moments (a) centre of mass [1] (b) 196N [2] (c) boy balances [3]

Q2 - Projectiles (a i) 11.84 ms is about 12 ms-1 [2] (a ii) 10.73 ms-1 [2] (b i) 1.3 m height [2] (b ii) 13.9m horiz distance [1] (b at top, a at bottom) [2] (d) drawing graph - like a stretched V shape with straight lines [2]

Q3 - Rocket questions (a) 0.21 ms-2 [2] (b) newtons law Q's [3] (d) rocket will slow down, 670 force slows down enough [3]

Q4 springs (a) energy is transfrered not destroyed [2] (b i) velocity = 3.3 ms-1 [1] (b ii) 1.83 yup [1] (b iii) 0.183J [3] I can't believe you get a mark for Joules here!!!

Q5 6 marker - graph goes higher I think? [6]

Q6 waves - (a) progressive waves moving through medium [2] (b) (I) 0.6mm [1] (ii) 0.08m [1] (iii) 22.7 Hz [1] (iv) 1.81 ms-1 [1]

(c) sounds r longitudinal, sounds can interfere [1] (d) higher frequency = less diffraction so lower amplitude and shorter spread [3]

Q7 difraction grating (a) tick violet [1] (b) constructive interence question [3] (c) 17.1 [2] (d) n = 3rd order [3]

Q8 refractive index diamond (a) 24.4 degrees [2] (b) 18.5 degrees [2] (c) draw the path [2]

(d) moissanite refracts more, lower critical angle [2]

(e) IR speed in core = 4.65x10^8 [1] (e) wavelength in core 2x10-6 mm [2]

(f) cladding, to protect core from damage [1]

Not perfect as it's a quick run through, maarks are in square brackets

Teachers aren't even meant to be in the exam hall and arent allowed to see the paper till 24 hours after. He was sitting reading the paper while we were writing it 😂

60-64 / 70 ... What ums do you think that is on this exam

Just a second I'll go contact the CEO of AQA and ask him for you.

Paper is sitting in front of me

Questions?

60-64 / 70 ... What ums do you think that is on this exam

Got to be 110 or above

Thank you how did you find it

That was my answer to that last question on the page. 'The forces have different magnitudes.' Did you think I was answering another part of the question?

Yep, you ready?
