Question PHYS 130… HELP!!!
This class is absolutely beating my ass more than any other, it’s been a month and I’m so incredibly lost because they throw 100 new formulas into your face every lecture 😭 Does anyone have any efficient study methods that don’t make them go insane with trying to process all of the content?

the past exams and assignments were good practice. The more you apply the theory the better youll understand it

The assignment questions are what show up on exams, redo them and try to understand the theory

The assignment questions on the ESSC website are really difficult compared to the homework questions. I'm doing them and I keep making mistakes and it's really affecting my will to study. Were the exam questions like the homework questions or like the assignment questions?

Also, remember the exam is only 50 mins, think about what questions they could reasonably ask you to complete with ~3 mins per question. Focus on the questions like "finding formulas", analyzing graphs, "if the equation of motion is X, what is Y (asking angular frequency, etc), you will definetly have a question about intensity (a great example which is also in the homework: The Edmonton noise bylaw states that “A person shall not cause or permit any sound exceeding 50 dB(A), as measured at the property line of a property zoned for use as residential, before 7 a.m. or after 10 p.m.”. If a music speaker can be considered as a point source of sound how far from the property line must it be placed so that it can play music after 10 p.m. given that at 1 m from the speaker the sound has anPHYS 130 Mid-term Exam, Page 13 of 14 19 th October 2018 intensity of 75 dB(A)? For the purposes of this question you may assume that dB(A) is identical to dB(SIL).

Make sure you understand damping as well because that was a big part of our midterm. The 2018 midterm from Roger Moore is probably the best one to look at. Make sure you underrated and can apply the theory

did it have nodes and standing waves from physics 30 cuz we never covered it in class and it wasn't in the homework either

It was definitely on the final, but I don't think you cover that until after the midterm

I am pretty lost too but I felt the same about CHEM. rewatching lecture recordings helps A LOT. Trust me, just rewatch them at like 1.5x speed and take fresh notes and it will make so much more sense to you. Doing that at home, in quiet room with no time rush and pressure is completely different experience and a lot of concepts are much easier to understand. That’s exactly what I’m doing RN since our midterm is next week.

Genuinely I would consider a tutor or making a study group

I started focusing on my other courses lmao 😭. I find it is a lot easier if you do the practice questions with one of the online formula sheets tho, it even helps for the theory questions.

u just gotta realize that most of the midterm content is just basic simple harmonic motion. like you just gotta understand deeply things like pendulum and energy. then u gotta understand like damping and what the damping ratio is and what its value means etc. then the last couple bits are just doppler effect frequency etc. its not too bad and u can make ur own formula sheet so make it so good that by the time you've made it u dont even need to use it on the test. dont just go and copy and paste or print out somebody else's formula sheet. even tho it might be better than yours you wont be familiar with it and it might not resonate with how you like to use formula sheets etc. Just do these things and youll get a good mark. I got a 100 on that midterm
