physics

My brother is in year 10 and is starting his subject selection process now, the school has not "recommended" him for physics so he is unable to do the subject. The school gives a recommendation for some subjects to dictate what subjects students can do. He is doing pretty well in year 10...

Hey there I was just wondering what my atar would be Would I need to ace externals to get a good atar?? I do Physics, Maths advance, Legal studies, Engineering studies,English standard I go to a rank 50 school in nsw My ranks are Physics: 44/55 Maths: 70/140 English: 30/151 Engineering...

hi guys, I'm doing English advanced, biology, business, physics and Math advanced and got my marks back for trials today. here they are: math: 45% physics: 60% biology: 85% business studies: 85% english: 95% my goal atar is 95, and i have gotten above 85 for every single assessment task for...

Can anyone please explain this in terms of emf and induction...? PLEASE🙏🙏🙏🙏

I am stuck on this module 6 electromagnetism question: 'Two charged parallel plates have a potential difference of 35.0 V. How far apart must these two plates be so that a point charge of -4.0*10^-8 C with a mass of 2.5*10^-6 kg will be exactly suspended against gravity?" I dont have a...

Could anyone with past experience with Sigma Science or knowledge about it please answer. I've heard a lot of good feedback about it, but want to hear from a student who goes there as well how they find it and what makes it different to other tutoring centres.

Hey everyone, I'm in the process of selecting my subjects for Year 11, as I will be completing the HSC in 2025. Right now I'm thinking: 1. Math Ext 1 2. Math Adv 3. English Adv 3. Chemistry 4. Biology 5. Physics or Legal 6. SOR1 (Compulsory) All the others are pretty much locked in, bio...

So basically I was watching a vid and this dude said when there is high density there is more collisions (which i understand why) but he also said they change the energy of the electrons' orbitals which I dont get how that relates to density........ This is my explanation to it but im unsure if...

Does anyone have any past papers of prac exams where content knowledge is not assessed and only skills are included (i.e doing the prac, validity, uncertainties, graphing, reliability, estimating using the line of best fit, etc. etc.)? I'm doing an assessment like this soon (no content assessed...

i’m a current year 11 student studying at a top 10 selective school, and I’m deciding whether I should do physics coaching at ace or matrix. I’ve heard mixed opinions on ace and matrix but sigma has mainly positive reviews. I’ve finished module two study at my old physics coaching and I think...

Hi guys. I am currently in year 11 and thinking about year 12. I currently take 3U math, physics and chemistry (and other subjects) and I am thinking about dropping physics and do 4U math. I personally like both physics and math but I need to make a choice to drop either of them next year. I've...

I just finished my first assessment today and I felt really dumb. honestly the first module is so easy and I made so many silly mistakes and I don't know what to do. I really enjoy physics but now I am thinking about dropping it next year... I don't know if I can get an A in the assessment. how...

Hey all, For an experimental report / depth study (with the theme of 'Analyse electric and magnetic interactions due to charged particles, currents, and/or fields.'), I would like to make an experiment that involves the motor with a gear box as seen in the attatcehd image (Single Motor 4 Speed...

Hey all, I will be conducting an experiment and writing a report on it (depth study) based on the theme of: 'Analyse electric and magnetic interactions due to charged particles, currents, and/or fields'. This experiment must be 'engaging' / creative (because otherwise, I lose marks in the...

Hi everyone, Justin here from ACE. In case you missed the last post, I graduated from James Ruse in 2016 and am now the Head of Chemistry and Academic Lead at ACE. I am excited to post again to let you know that our new series of completely free online seminars which review each Module in the...

Hi, What are the best ways for one to improve their responses in theory based questions. The numericals are fine, however I am noticing that I am consistently losing an average of one mark per question, on the theory based questions. What is the best strategy to improve my marks in these areas...

Hi, What is the best revision strategy to stay fresh with content especially for physics and chem? I have noticed the test papers ask very niche questions, where you are required to remember very small details about all the chapters in order to go up to the higher b5/b6 mark. So how often...

A question popped up in a physics textbook and I would just like to clarify my answer: a) My answer: Potential difference is positive so ΔV = ΔU/q and since potential difference is positive so must be ΔU. ΔU = q*ΔV = (-1.602 * 10^-19)(100) = -1.602 * 10^-17 ΔU = -ΔKe -1.602 * 10^-17 =...

Can anyone recommend experienced online physics tutors? I live pretty far away from the city and wouldn't be able to do in-person classes, however can come down to Sydney if classes are held on weekends. I need a tutor that's able to teach just as well online as they can offline, and keeps...

Hi, I have a practical process task for mod 6 for both chemistry and physics so what are possible things they may ask us to do. Additionally, how would you guys recommend I study for these sort of tasks, and what is the best approach to maximise marks? Also if anyone has any past papers of...
