The equations in that paper are incorrect. I can elaborate if anyone is interested.

I posted a corrected version here:

Thank you Ether,
I'll read through your paper as well. If I have any questions I'll post them in this thread.
Elaboration on the equations would be appreciated.

Thanks again,
Garrett

Equations 12 and 15 on page 5 of Morrison's paper are not correct. The X (horizontal) component of force Fx on the frisbee is not equal to F_D. The Y (vertical) component Fy is not equal to F_L. All the subsequent equations derived from 12 and 15 are therefore not correct.

The correct equations for Fx and Fy are given near the bottom of page 2 of the paper I linked.

Thanks again Ether, I'll keep that in mind as I review the papers.

Just a note, as far as our school informed us, EE submissions are property of the IB and aren't allowed to be published publicly.

A team member sent out an email at the beginning of the season to us about the physics of Frisbees. I have not read through every link inside, but in case it may be of help, here is a link to it: https://docs.google.com/file/d/0B1Dc...it?usp=sharing

Thank you Dan. I'll meander through the links over the weekend

Makes sense, I'm going to shoot an email to my school's IB coordinator and confirm this. The IB has made a lot of changes in the past two months and I want to make sure that I have the proper info.

Thanks for the heads up,
Garrett
