    B Help with IB Extended Essay Physics Experiment Ideas

    Sure! "The IB Extended Essay, or EE, is a mini-thesis, you will choose a research question as a topic, conduct the research independently, then write an essay on your findings. The essay itself is (maximum) 4000 words." I'm doing mine in classical physics and looking for some inspiration for...

    B Help with IB Extended Essay Physics Experiment Ideas

    I'm having trouble coming up with a experiment to investigate for my IB Extended Essay as well as formulating my research question. Does anyone have any recommendations on similar (in terms of classical physics & abundance of background theory) physics experiments that can be done?

    B Calculating Uncertainty of Mean for 0.5 mm Ruler Measurements

    I apologize, obviously you can't see what I have written down. I actually read the whole PDF document, instead of just browsing over it and now I understand what I'm supposed to do. Here's the data I was referring to: What I've done here is logical, right? I can now use Δxavg in my graphs...

    B Calculating Uncertainty of Mean for 0.5 mm Ruler Measurements

    Would something like this work? Or would that contradict this? I have equations for the rest of the quantities before Table 5 employed in previous tables. Hence, whey there is only one equation and calculation. Thanks for the replies :)

    B Calculating Uncertainty of Mean for 0.5 mm Ruler Measurements

    I am following this: avntraining.hartrao.ac.za/images/Error_Analysis.pdf I have a ruler with an uncertainty of ± 0.5mm. I made a calculation subtracting one measurement of the ruler, from another measurement, making the uncertainty for the data ± 1.0mm. As I have four trials, I calculated the...

    B How can I linearize my (negative slope) quadratic graph?

    Just for some closure, I consulted my teacher and was able to explain thing a bit better in person. You were all correct and there was no way to linearize the graph. My hypothesis was wrong. Through the graphical analysis, the actual relationship was quadratic and there was no power relationship,

    B How can I linearize my (negative slope) quadratic graph?

    My problem: In my hypothesis I state that the equation to solve is s = u*dt and I need to solve u and t. Honestly, i didn't quite understand how that would help, I just tried something I was suggested. I'm basing this part of my research on my physics textbook which says this: Also, off of...

    B How can I linearize my (negative slope) quadratic graph?

    I have spent some time with my problem. Here is a summary of where I'm currently at. When reversing my graph's y-axis I can almost get an almost perfect line. This line gives me the correct slope and intercept, if I insert the distance in reverse. i.e. if I insert 50mm distance into my equation...

    B How can I linearize my (negative slope) quadratic graph?

    The beam is a double overhanging beam of 1000mm with 50mm overhanging each end. So, 900mm between the two pivot points. My diagram:

    B How can I linearize my (negative slope) quadratic graph?

    That is my equation for sag. My power of t didn't transfer over from word, sorry. For my investigation sag is the amount of vertical depression the beam endures when applying a mass at different points from the midpoint of the beam. Distances of: 0.0, 50.0 100.0, 150.0, 200.0, 250.0, and 300.0...

    B How can I linearize my (negative slope) quadratic graph?

    I had accidentally used a different graph in my previous reply (which I didn't delete fast enough). I plotted it using the same dataset as my original graph, but reversed the y values. Now onto what we discussed: From what I understood, I plotted two graphs: ln(d)^2 and ln(d^2). However, they...

    B How can I linearize my (negative slope) quadratic graph?

    I am doing an investigation of how much a beam sags, based on the distance from its midpoint. This is my hypothetical equation: The relationship between distance, d and sag, s is not a linear relationship. Below, is the determined relationship between the variables, linearized by natural...
