Reply to Comment on “Calculated Trajectories of Curling Stones Under Asymmetrical Friction: Validation of Published Models”
In a comment to our published work [1, 2], Shegelski et al. question our conclusion that the motion of curling stones cannot be accounted for by a difference in the magnitude of the friction force between the leading and trailing halves of the stone (i.e. a front–back asymmetry). Our view is that their criticism is mainly due to unfortunate phrasing from our side, and that this has caused us to discuss fundamentally different phenomena.
Mechanisms that in one way or another result in front–back asymmetry of the magnitude of friction forces are often proposed as explanations for the motion of curling stones, especially in popular science. The purpose of our publication was to investigate whether such asymmetry is in fact capable of producing the observed behaviour. The investigation was performed using a computational tool developed for this purpose, which calculates the motion of a curling stone based on a given distribution of the coefficient of friction along its contact annulus, and...
