Flight properties of discgolf disc
Valík, Tomáš ; Sekora, Jiří (referee) ; Hanák, Petr (advisor)
Even through the rising popularity of disc golf all around the world, there aren't many solutions on how to compare individual throws, other than by observing. By placing inertial sensors on the bottom plate of the disc, an average rotation frequency was obtained by an algorithm. By comparing six methods of evaluation with reference values measured with the Qualisys system, the best method returns an average percent error of 2,66 %. Based on this result a test comparing two throws, backhand and forehand, was made, with average values of 14,22 and 11,46 revolutions per second. Two sample t-test rejected null hypothesis at the 0,05 significance level with p-value 2,101*10^(-18).
