Thanks. I agree that at this point I'd have to evaluate the uncertainty more to see if there's really that much of a disagreement between the calculated coefficient and reasonable values, and I appreciate the suggestions for why it could still be higher than expected (not a smooth sphere, wave...
It was hard to find sources of information on drag coefficients for this situation. Most of what I found was for low Reynolds numbers. I calculated a Reynolds number of around 2e6 (based on an average speed of 480 m/s, size of 0.076 m, and air dynamic viscosity of 15.52e-6 m^2/s) which I can...
Judging from the lack of distortion in the corners of the slow motion video, I don't think the lens would cause too much trouble.
As for the position and orientation of the camera, the camera seems to point straight at us while the stakes are lined up across, almost lining up with the plane of...
In a recent video from SmarterEveryDay, a baseball is launched from an air cannon faster than the speed of sound. I used the video with my 2nd year HS physics class, and we put the high speed segment of the moving ball into Tracker (video analysis and modeling tool).
We found that the drag...
Here's a Desmos solution, if you're still looking. Your students might come in familiar with Desmos from math classes. For IB physics, students are supposed to play around with maximum and minimum slope lines to get uncertainties which is how I started playing with it. Here it is with those...
