Homework Statement Drop the ball you have been given and watch it bounce: once and rebound, twice and so on. What could we measure in this process? What variables could change? What would change? Now investigate anyone aspect of the bouncing of the ball. This is my research question: How...

hi. i was wondering if it is possible to write a well developed essay explaining the physics behind tae kwon do (korean martial arts). think an indepth version of the show "human weapon". do you think that the research will be too simplistic/ complex? how should i narrow or broaden this topic? I...

Hi there, I'm sorry if this sounds incredibly vague, but I'm having difficulties narrowing down the research question for my Physics EE. I'm sure of the field I want to do it in: acoustics. The problem with most experiments involving applied acoustics (ideal room sound, etc.) is that, unless...

In a particular binary star system, star A has apparent brightness 8x10^(-13) and star B has apparent brightness 2x10^ (-14). a) Explain how it is possible to deduce that star A has a higher luminosity than star B. b) The surface area of star B is 10 000 times smaller than that of Star A...

Basically the extended essay is a piece of independent research done during the course of IB. I'm planning to do a physics EE, but now it's mid April and I still failed to find a simple yet specific topic to do reasearch on. My last few ideas were too complex or not specific enough. My...

Hi, this question is a part of an 'online homework packet I received through my IB 11 SL course (ie. International Baccalaureate 11 Standard Leval). I submitted my first attempt to answer this question and had the wonderful "sorry your answer is incorrect" screen pop up. I was wondering if I...

Im currently just over half way through my IB diploma course at school with a predicted grade of 39-43 out of 45. This translates to a UAI (university admission index) (its a New South Wales thing in Australia - ask me if you need help here) of 99.45. I would really like to study engineering in...

I teach an AP/IB physics class in a high school. On the last IB ("International Baccalaureate") examination, there was a question about friction that went like this: [an object was described to be at rest on an incline] "Show that the object must start to slip when the angle of incline is...

IB physics extended essay HELP! tis the season to start stressing over extended essay and i need help. i am planning to investigate how different angles of airplane flaps affect the lift of the plane when the plane is taking off or landing (because that's when the flaps come out)- you know how...

I'm planning to do an extended Essay for the IB Diploma in Physics. I want to do something on Fluid Dynamics. I was thinking of investigating terminal velocity and effects on drag and upthrust to terminal velocity. That investigation will of course involve Stoke's Law. BUt I think that might be...

Hey everyone, I have a chemistry lab that I have to set up for monday, and it is very open-ended, meaning we (the "scientists") design and perform our own lab according to some general guidlines. So I was hoping that by posting this here I would get some expert suggestions. "You will be...

Hey everybody, I'm doing my International Baccalaureate extended essay (2500 to 4000 words) in physics, which means basically i need to come up with a research question and hypothesis, then design and procede with a lab to answer this question. For example a guy at my school last year did...

Hi! I have been accepted in the IB program (I will be entering freshman year next year). I am aware we have a multitude of IB or AP students here so I have come to seek advice about what I should do to prepare for the classes that are offered. I have heard they are of immense difficulty, and...

Hey all, new here so don't know if this is the right place to ask this: Is there an online version of the IB Math formula book anywehere, for instance an adobe .pdf version. Earliest 2002 version. Thanks in advance to y'all

Hi, I'm in IB physics and I'm having a little trouble since the teacher would rather play computer games than teach us (the book isn't great either). Right now we're working on force and I was wondering if anyone could clarify a few things for me please.I'll just work through some problems and...

I have a few problems: Solve 1. 32^2x = e e^2x +1 I cross multiplied and got 3e^2x = e(e^2x + 1) Then: 3e^2x = e^2x+e And now I don't know what to do from here... 2. Solve e^2x - 5e+x + 6 = 0 This one can't be factored, so does the quadratic equation work here? If so, how...

I've been working on these problems for a long time trying to prove to myself that I'm not stupid (though I am convinced I am because I don't feel like "IB material" at the moment), but this will be impossible since I have other things to do. So, my two questions are these: 1. An arithmetic...

Hello all. Does anyone know any good sites which outline physics principals and equations? I used to use [PLAIN]www.physics.uq.edu.au:8001/ph128/contents.html,[/URL] but it seems that it has been shut down. I really liked the site, since it was comprehensive, and had a huge amount of...
