Nice job! Have you tried using the DataTool built into Tracker to get the linear fit to omega vs t? Just double-click the plot to transfer the data to DataTool, then in DataTool choose Analyze|Curve Fits. Faster and easier than transferring to Logger Pro.
Hi this was really helpful as I am using the same method to analyze the motion of a spinning top from slow-motion videos (120fps) I clicked on iphone and the only thing i'm unable to understand is why the angular velocity graph shows a frequently oscillating line for me and not an almost straight line like yours, do you know of any possible reason for this?
I can't find it - I made this so long ago... However, it is easy to record: just shoot it from above. If you don't have a turntable, you can do a screencast of something like this: phet.colorado.edu/en/simulations/rotation, and track the video...
To autotrack points you have to enlarge red square, that appears when you select point with ctrl-shift

You’re helping me a lot thank you :)
Maybe you've found out, but you can change the size of the auto tracking template, allowing large markers.

Hi when we perform what would be the depended and independent variable
For some reason it doesn't give me the omega, any help?
Hey, can you send the software link?
found it
can you link the software used?
Sure: physlets.org/tracker/
It is an awesome piece of software!
Can you share the video used here?
