There is a very heated debate in a forum for airsoft that I frequent. It is about what happens to ba bb pellet when it is fired from a bb gun. Two point of contention have formed. 1. A unbalanced bb, who's geometric center is disparate from it's center of mass will wobble, or oscillate on the y and x axis due to it's imbalance. 2. The opposing view is that all spinning objects spin around it's center of mass and travel a linear parabolic path and thus it is impossible to wobble. So which is true? Here is a link to the thread of that discussion. http://forums.airsoftmechanics.com/index.php/topic,8507.0.html Thanks for your responses!
