As someone who took his last physics class 20+ years ago, but did a fair amount of interviews for recruiting, I really appreciate the design and progression of the first two questions. It starts off with a simple second derivative, which should remind people of acceleration which is proportional to force. The equation therefore states that force is inversely proportional to displacement, the classic oscillator description. It then goes on to a floating buoy, which common sense tells us will bounce till it quiets down, so a damped oscillator. Analyzing it with a force diagram, the change in buoyancy force is proportional to change in volume submerged. But since the object is spherical, the change won’t be uniform and it causes the dampening effect. I would be looking for the interviewee to ground his explanation more in physics and link up the two parts.

They’re just trying to see if the student can systematically work out a solution to these problems with logic, connect to broader points, genuinely explain every step of the way without it being spelled out for them. This is easy even if you’ve taken 1 or 2 physics classes in high school or university that spell it all out for you, but most high schools don’t cover material to this extent. It’s definitely a challenge to reorganize all your thoughts, and systematically work out steps that will get you to your solution even as a university student. The explaining is what deters you the most, and puts pressure on you.

Good job! I've been in a maths intense path myself and I still find the candidate quite good. It's not as easy as it seems to navigate between physical interpretations and maths expressions. He never said anything senseless, every single word he said was relevant. He didn't rush, took the time to think and answer from basic principles and observations. The concepts look clear in his mind, he hasn't been lost in overly abstract and calculation driven tendencies. He's probably not your strongest maths intensive candidate but he looks like a good allrounder that has high chances of doing well as a Physics major which is what the interview is all about, they're not looking for Olympiad contestants.

When deriving the net force acting on the sphere shouldn't we consider also the force of gravity acting on the small cilinder? in that case the net force would be half of that calculated by the student. This would make also more sense since is exactly gravity that then let the ball oscillate back down.

I think he is linearizing the behaviour in the equilibrium point, keeping only the first order. In this way he assumes that the difference between force pointing towards the bottom (mg) and the force pointing towards the top (Archimedes) is proportional to y, so when the sphere is above he simplifies the excess of mg contribution as an equivalent opposite force proportional to -y.

Regarding the bit about the negligible buoyancy of the air (at around 22:00). I don t think there is any, since there is no air underneath the section of the ball to move it upwards. There is only pressure from above so i don t think it s really relevant. But if anybody has a good explanation about this please tell me. Thanks!
@Wksfr

Interesting question. I think the buoyancy effect due to the fluid above eg air would be calculated in the normal way, even though there appears to be no bottom surface on which it can provide the buoyancy - the pressures “work through”. If it was oil above you would take into account the buoyancy effect - the weight of oil displaced. Regardless of their being no oil underneath. This may not help/ be relevant, but I think of archimedes principle by imagining a volume, which can be any shape, within a fluid ( eg a brick shape, or sphere, or anything). If the fluid isn’t moving then the upthrust on that “shape” must equal the weight of the fluid, otherwise that bit of fluid would move up, or down. Seems obvious, but I can see how it was a eureka moment. That’s why for floating ice, the weight of water displaced =upthrust = weight of the ice. So when the ice melts it must exactly fill the original volume it displaced.ie water level doesn’t change when it melts.

Wait, how did u get a rectangular prism? If we take really small values of y, lets say dy, the 2 bases are circular and the lateral surface (with height dy) is almost perpendicular to the two circular bases. Also, if dy is infinitesimally small, the two circular bases have the same surface area. This gives us a resulting figure of a right angle cylinder with the height dy.

The main points that are considered in an application to Oxbridge are: predicted grades, teacher references, personal statement, PAT (physics aptitude test, in this case) score and interview performance. Since we only get 5 university choices to apply to, only the people that even apply are the ones that have a good shot at a place. They all study their subjects at the highest level possible (in this case, it’s likely to be A Level physics, maths and further maths, and possibly another subject) and are predicted to achieve top grades in all of them. Then out of those, the students that have best proven their capabilities in physics and maths in the pre-interview assessments will be selected to interview. They aren’t testing their mathematical ability here because they are already assured of it from the previous stages of admissions. Then the interview tests another important quality needed to succeed, essentially, how teachable they are.

If I have already achieved the requisite American qualifications, but I have more AP exams in May, should I expect any potential offers (whether from oxford or elsewhere) to be conditional on basically 'exceeding' what is stated on the website? Some, but not all, of my pending scores are in subjects considered 'helpful but not required'-would a potential offer require me to score well in these exams on top of what I already have? I suppose you could only speak for Oxford, but I'm a bit confused about American qualifications and any insight/clarification would be greatly appreciated!

@@user-yr9nb2bw1m if you listen to the explanation in the video he’s explaining why the shape of the graph is sinusoidal. If you know how to solve the 2nd order DEs the general solution turns out to be y=A COS X + B SIN X where a and b are constants to be determined based on initial conditions. But just follow the explanation in the video and you can do it without knowing how to solve DEs

@@harinachiappansubramanian9206 I suspect there is difference between the mock interviews and real interviews. Not sure really because of difficulty level or stress. When my son watched the mock interviews, he had no patient to finish watching them because he had answers almost immediately. But when he had interviews, obviously he made small mistakes here and there, and had hints from the tutors as well. The interviews were absolutely great. He enjoyed all the interviews very much, but then he was not so attached to the outcome, so less stressful than otherwise.

Eh, that's a rather abstract application which technically doesn't obey physical principles (as 3b1b pointed out himself). It's similar to the analogy that a person's displacement as they fall through the Earth is the same as one modeled by a spring (it is!). Of course you can mention it to show your passion, but using it to actually solve a problem or to show your complex understanding is a little odd as it's not a conventional solution + it can in circumstances be a 'cheat,' like with the 'falling through the Earth' question it's an oversimplification and maybe the interviewer wants to see your calculus abilities and your knowledge on approximating the force within a sphere of uniform density. In this case however, using Snell's Law would be a very intuitive approach as it is not an analogy, it is a perfectly valid solution as it solves for least time
@avlbest096

@@dakerbal of course the go to method here is Snells law as that’s more inline with courses taught in A-level. The spring analogy is just something you can mention to show background reading or passion for physics in general.
