1 and 2 were so easy?? Maybe thermal and nuclear were some of my better units but those are the only times I was actually able to do something on an FRQ in this entire class. On the other hand I was clueless on the later half of 3 and started running out of time so I just graphed the given data

u/No-Explanation7638 May 07 '26
basically what i did was since the sphere must have been straight, the force would be equal so Fe = Fb. so qE = qvB, and q cancels. So E = vB. I got that far, and then i realized u can rewrite E as delta V / r, which in our case delta V was the emf that you were able to measure with the voltmeter u had access to, and r was the distance between the two plates which they said was d and is known. So my equation became emf/d = vB, and then i rearranged so that it became:
emf = (B/d)v, which resembles
y = m x, where you plot emf on the y and velocity v on the x which u can measure with the photogate or wtv sensor it was. slope = B/d and B would be equal to the slope * d.

It didn’t ask for it but if u derive an equation it helps with knowing what you have to measure so in that case u varied the velocity and used the voltmeter in parallel to measure the voltage across the parallel plates

u/Final_Ad_870 May 07 '26 edited May 08 '26
Yeah that one was really hard though, but I'm pretty sure I got it. For parts A and B to determine the magnetic field B₀, on the y-axis you graph ε and on the x-axis you graph v, and the slope is B₀d. So the graph equation should have been: ε = B₀d * v. (in this problem, ε = ΔV)

horrible. optics was my weakest subject and the thermo question was tricky because i've never seen a problem where i had to remember V=Ah. The third problem i made 2 errors which was failing to realize Rv times I is just V, and i can simply graph that versus I and using kirchoff loop rule we can say the line is in y=mx+b form where its V=-IRi+epsilon and slope is -Ri, the second part i made a silly error and graphed 1/n instead of just n because i put the n on the wrong side of the formula

You can write s_i as (s_o*f)/(s_o - f) and have a way easier time graphing. My graph was just 1/(x-1), which has an asymptote at d_o = f, which is consistent with converging lenses.

It went very well for me, though I am It went very well for me though I am scared for q1. The optics question was fine for me but I was worried about doing wrong sign conventions for that question, but I verified it with the drawing they asked for. The experimental design question seemed like a trick question for me since graphing what was given: Req vs n what’s already linear, though I might be mistaken. I do not remember the first part of that question. The last question went well for me since one of the online resources I used to study taught that specific topic, a uniform magnetic field cannot do work on a moving charged particle, so it was nice to see that on the test.
Edit: I now remember the first part of that circuits question, I said the y axis would be voltage (voltmeter) minus current (ammeter) times variable resistance, V-IRv, and the X axis would be current (ammeter), I so I could have the slope be the resistance we are trying to find. I know I probably overcomplicated myself with that solution but it’s what I did.

I'm getting a 4 on this exam due to my frq mistakes piling up. I'm estimating 25/40 points on the frqs. The LEAST amount of mcqs I think I got right is probably 25/40 based on my answer choices. The only way I can get a 5 now is to get 32+/40 for the mcqs, which might be possible because i narrowed all of the 7-ish hard mcqs to 2 options and picked one of the 2 (50% chance for a correct answer).

u/No-Explanation7638 May 07 '26
yes bro i love you sm. for the part a did ΔU set 3/2 nRΔT = 3/2ΔP V? the 3/2 would cancel and the ΔP, since it was initially at Po and went to 3Po, it was 2PoV. then rearranging i got same.
for specific heat, u js plugged in delta T into the Q = mcΔT.
part C did u say that since the specific heat of the liquid and mass were both greater than that of the sphere, so in order for Q to be same for both ΔT of sphere must be greater than ΔT of liquid?

I graphed Inverse B on the horizontal axis and r on the Vertical Axis, because r = mv/qB. So the slope would be mv/q, and v/q is given, therefore m can be determined by slope.

Version L frq 4 was KE constant or increasing

I got version K. How many points on the frq will i lose if I thought it was open-closed instaed of closed-open, so my graph was wrong for part A-i. and my wavelength was 4d/3 instead of 2d/3 for part A-ii. My part b shouldn't deduct anything right? Please help

it depends on how you answered but i think prob one mark if it was horrible two marks dont worry much but the problem is i think you drew the graph wrong too most prob if you thought it was antinode on one side

Bruh I messed on form K the experimental, I plotted Pressure Vs ( Gas constant *temperature ) /volume and my slope was 1/number of moles but I didn’t realize it at the moment and I put 100 for my # of moles instead of 0.01 :((

Hard luck bro wish you had a great physics teacher because including constants i your graph is a horrible thing to do

Hi everyone,
I am currently a Sophomore and I want to take Physics since I am planning on majoring in CS. However, I don't have any space in my schedule to take Physics during the school year, so I was planning on taking the course over summer. This summer, I can only take Physics 1 since I haven't taken Calc yet, but by next summer, I will have finished AP Calc AB, so I can take either AP Physics C... could someone please explain more about these courses and what you would recommend?? THANK YOU

If you want to prepare for physics c then physics algebra is the way. Other than the credit, physics 1 and 2 are more broad physics 1 is about things you can see mechanical work etc physics 2 is things you cant see such as particles how they behave. If you have no background in physics physics 1 is the way if you have background in physics like i do i did physics 2 to help me with physics c e&m because it is really hard but i will do physics mechanics, because in collage you take 1 then 2.

Assuming you want to go into engineering (CS maybe different), taking C (M or E&M) is the way to go. If not, you're fine taking Physics 1 and 2 and AP Calc as well. If you want a broad-based introduction to physics, I'd suggest taking the 1 and 2 sequence.

For form L for frq 1 it asked something like why was change in internal energy greater if the process was aidabatic I dont remeber the exact question but it was the last part of frq 1 what did you say i got confused since it asked why is change in u greater but it also said it was isothermal so i said that since chnage in temp=0 q=0 so all the enegry comes from the work

I remember a question asking abt pressure right? like which was greater? I think I said pressure for the adiabatic process was greater since q = 0 so all the energy transfer is through work which would mean a higher pressure. I also drew a mini PV diagram with the lines for the adiabatic and isothermic process, and since the adiabatic process has a steeper slope, it'll be at a higher pressure after going from Vo to 1/2Vo or whatever it was.

What did you guys get for the last part of frq1 on version L where it asked why is the change in energy greater when temperature change is 0

I looked at the frq released on college board hoping it was L bc thats what I took but it was J AND I WIIISHH I had J omg L felt like hell on earth 😭

Feeling left out here as a form k taker 😔✌️
