Hello all! This is my first post on the forum. As some background, this issue pertains to the IB Physics Internal Assessment that I am in the process of writing. Thanks in advance for your help!
My research question is: How does the drop height of a consistent-size clay ball affect the extent to which it is compressed? My independent variable was the drop height of the clay ball, and my two dependent variables were the vertical compression of the clay ball and its horizontal expansion. I have already taken data for the experiment, but I'm not sure I need to post it here; if anyone would like me to, please let me know. I also graphed my data, and the best curve fit was a natural exponent function. There was a moderately small RMSE.
Not entirely sure; that's what I'm wondering.
So far, my "solution" is very qualitative and lacks real mathematics. I essentially just explain that the graph's leveling-off makes sense, as a ball can only compress or expand to a certain degree within the restraints of real-world physics. What I'm having trouble with, however, is determining a). whether or not this curve fit is correct, and b). how to mathematically explain what I have observed. Thanks!
