OCR A Level Physics Modelling physics H556/01 - 26 May 2022 [Exam Chat]

I don't do physics but do OCR chem and bio, just wondering how helpful the advanced info was. Was the gravitation fields question a big question? Also do you guys have multiple choice questions at the start of the paper? Were they all in advanced info?

hell no there is no question about experiment in cosmology

There was but is was more obscure - it was the 6 marker for the graph of lg(L/Lo) against lg(M/Mo) where you had to find b. It was the gradient of the graph.

not a big question, but it was a main one not a multiple choice. multiple choice was a blur but pretty sure they can be from outside of advanced info

there was a whole question about circular motion and gravitational fields, neither of which were on the advanced info, but apart from that I guess?

Circular motion is included in the SHM topic

Does anyone know what they got for the pressure question calculating the difference in pressure in the U-shaped tube to the outside. Fairly sure I got that one wrong. Density was 1000, and distance was 10cm (x=5cm)?

but it did specifically say oscillations

The multiple choice was actually not too bad. The gravitational field question was a fairly big question (can't remember how many marks sorry) but links to a topic that was mentioned in the advanced info so i figured there would at least be a 1 or 2 marker. My advice would be to revise topics that have links but definitely focus on the topics mentioned. The advanced info was quite good with respect to the weighting of marks, with the topics with the most marks higher up the list.

Does anyone know what you had do for the six marker on the tent question?

U had to use p=hpg and put in the difference in the heights to get the difference in the pressures

I think I used rho = phg1000 x 5x10^-2 x 9.81

Thanks guys, I hope you guys smashed that paper - especially being the first science OCR alevel and going into that blind

Not sure if it’s right, I mentioned making it triangular to increase impact time, reducing the surface area, attaching the ropes higher up to increase perpendicular distance from pivot and they gave the number 40 so I calculated the UTS required in a rope to withstand the tensile stress
