Hello everyone! After finishing my IB Diploma, I decided to share my personal study material for Physics! Therefore, I developed a free website, which is basically a transcription of my personal revision notes that helped me achieve a 7 with 92% in Physics HL in May 2017, along with useful links, exam tips and recommendations! The HL part is currently being developed, along with Option B! Link: https://www.ib-physics.net/

Hey fellas, As you saw the title, I need urgent help with my Physics IA. My central topic is holography and the specific one is understanding light as an electromagnetic wave. So, in that order of ideas, I'm working with holograms made with the reflection of a laser through a splitter beam (Below you can see an image that shows the experimental set-up) Im. 1 I did this set-up and collected all the data and stuff but now, I don't know what to do with this data. In a first instance, I wanted to create my own hologram. But considering that I'm not doing anything special, it's not a 24-points investigation. What do you guys think I shall do? I'v…

Hello everyone For my Physics Internal Assessment, I want to write about computer simulation about Stefan- Boltzmann law. I want to do a computer simulation. But it's about this law and I want to compare it to another simulation too. What do you think should I include my own simulation(i won't talk about it too much in my IA)? or should I use someone else's simulation because making my own simulation sounds like a little computer science stuff. By the way, I can make one so it's not problem for me Any help will be appreciated

hi guys, I really need your help! I was supposed to do my IA using a physical pendulum, but then my teacher and I realized that it's too complicated and now I have to do something else. Since I don't have much time, I wanted to do a "simple" experiment that doesn't require expensive material and a complex procedure. The areas I'm really interested in (personal engagement) would be guitars (so an experiment on standing waves maybe?) and global warming/renewable energy (but I don't know what kind of experiment I could carry out with this topic), but I appreciate any kind of suggestion. Also, as I understood, carrying out a traditional experiment is the best way to get…

I want to paste graphs, tables and other things like that into my IA. I will reference them as well. I asked my teacher but she is like 400 years old, doesn't even answer my question properly, in fact she doesnt even want to answer the question. "Im on vacation stop messaging me". I found a graph from my physics book as well, can I paste and reference that too?

Hello guys, I have query about how everyone prepares for their unit tests in HL Physics. Someone recommended me the Tskokos text book for preparation, the question bank I have all the versions and do all those worksheets my teacher provides in our class. My question is are these things enough to prepare for an unit tests especially at Physics Hl. Can someone please share their experiences. Also can someone please explain why do people call Physics Hl so hard. I mean are the unit tests completely different to whats done in class? Is this rly true. Will be appreciated.

Good day guys! Is anyone here familiar with European universities? I am currently at the end of IB1 and I was wondering if most universities accept Physics SL as one of my courses. I am currently taking Physics HL but I am in great doubt that I can finish the course successfully as my Physics teacher is highly unfamiliar with the IB and can't teach. We covered 3/4 of the syllabus but none of the topics in great depth. I tried attempting past papers and found it extremely difficult (this includes the rest of the class) and most of us couldn't score past 30%. I am on the other hand taking Math HL with a predicted grade of a 5 which makes me wonder if Math HL (5) …

So I have written up about 90% of my physics IA, and with my results, I did not get any data that linked to my theory or to my hypothesis and discovered my method did not collect data for my investigation topic. I found a new prac that could potentially fix up this mistake. Is it worth re doing the prac, meaning redoing all the results, or just talk about the new prac in the discussion, and why my method was incorrect? My IA (If you were interested) Looking at vibrational nodes in a tennis racquet by looking at the COR by dropping tennis ball on different parts of the racquet. The bounce height was linear and positively progressing, instead of producing a…

I am working on an IA about sugar and refraction. I failed a few times already and i really need some help, here I'll talk about how i did the experiment, and see is anyone can help me: I have a rectangular container made of glass ( 8cm/5cm), a laser pointer, water, sugar, and paper I shoot the laser in at a fixed angle into the container, recording the incident ray and the point where the ray goes out I predicted that when I add sugar, the refracted ray will bent more, but no matter how much sugar I added into the water, the ray always go out at the same place Is it because the container is too small? or should I not use this way to test the refractive ind…

Hello, I'm basing my IA on bifilar pendulums and require the formula of the time period of a bifilar pendulum and simple pendulum. When I researched online, different sources claim different things. One formula I obtained was T = 2pi*(L/g)^0.5 (2 times pi times square root of L/g), where L = length of the pendulum and g = gravity. Is this formula applicable for both simple and bifilar pendulums? If not, what is the formula for each kind of pendulum? Thanks in advance for the help!

I conducted my physics IA experiment recently and I would like to know something. The aim of my experiment was to measure capacitances' of different capacitors by discharging with a hand made machine. I measured the capacitance by using the rate of discharge and plotting it on a graph. Then I used the gradient and a formula to calculate the capacitance. So know I am wondering if I had to add a dependence, by that I mean like discharging capacitors under a specific condition. Is this necessary for the IAs or can I just write up the way I did. If I am supposed to add a condition what would the highest mark achievable be if I didn't add one.

So I chose to make my physics IA on fluid damping. The whole experiment is basically a mass on an oscillating spring and how it damps into a beaker with a different concentrations of sugar water solutions. my teacher want me to find a way to detect the amplitude of the oscillating spring. The whole experiment in the end is supposed to give me an exponentially decaying graph. Any idea on how I can somehow detect the amplitude. This is the website I found my experiment in if you dont get it. Its "Idea 8". PLease HELP MEEEEEE: https://physics.guzled.com/updated-16-ideas-for-ib-physics-ia-investigations/

Hi guys, I have an idea for my physics IA (SL) that involves bouncing a ball on a material (unsure of what material to use) of different thicknesses and measuring the coefficient of restitution. However I am unsure if changing the thickness of the material will make an impact on the bounce of the ball and have been unable to find any information online. So I would like to know if the thickness of different surface materials affect the bounce of the ball. Any help is appreciated, thanks

I´m really into Math(my fav subject) and I love to learn about all this weird physics(like Rick & Morty). My dilema is that I really don´t want my IB to be a headache, and neither I would like my averge 7 to get worse.

Do you guys think speed of wave vs depth of water is a good physics IA topic? I will use something to prop a plastic container filled with water to a certain height, drop the item to create the wave. I will do this multiple times with multiple heights of water. I will also measure speed of wave that has something added to it like salt or pepper, something that doesn't dissolve. Does this sound acceptable? my teacher has been ridiculous and I don't have a strong relationship with her. Any help is appreaciated as i'm very stressed.

Hello everyone, I'm back with some new free videos ¯\_(ツ)_/¯ This time it's about a workshop (six 10 minutes videos) to help you prepare for the Physics SL/HL exam. Here is an overview. Video #1. where you can get started with a simple quiz and learn: Which topic typically has the least marks allocated to it? And which topic the has the most marks? (same is true for SL/HL, Paper 1 or 2) Video #2: where you learn useful details about the exam, such as: The relative weighting of each exam. For instance paper 3 is relatively easy and worth as much as paper 1 (for SL) What IB means for complexity and nature of science, explained t…

Currently in physics, my teacher has disapproved my two previous proposals for being too elementary. One of my topics was dropping a tennis ball onto certain spots on the racket and seeing which spot on the racket bounced the highest to prove the optimal height for hitting a tennis ball. However she said it was too elementary but I could do it if I really wanted too. What are yall's thoughts or should I change my topic. If anyone has some easy suggestions feel free to let me know. Any help appreciated.

Hello, For my physics IA, I"m investigating how the time period of a bifilar pendulum changes with length of the pendulum and linear mass density of the thread. Is this too simple a topic for HL? Plus, I feel that linear mass density and the length of the pendulum are too related to be separated into two variables. I also don't get a very strong correlation for linear mass density and time period (even for a cubic curve, the R2 - correlation coefficient - was only 0.927). Any help will be appreciated and thanks in advance!

I asked a similar question previously but I'm asking again about something slightly different. I'm writing my EE in physics, and my research question is "how does wavelength of light affect the energy output of a photovoltaic cell?" I'm planning to use different lightbulbs which have different wavelengths to find out how the wavelength affect the voltage (or current) of the solar panel. Some example of those lights are: incandescent bulb, fluorescent bulb, LED light, sunlight and UV light. Since I'm not very confident in physics, can any physics genius tell me whether this is a worthy experiment? What if the wavelength doesn't affect the voltage (or current)? I really nee…
