I'm designing a very simplistic particle simulator. Particles are dropped on a spinning disc and then bounce back (although lose some momentum due to the friction of the disc). I'm working with an arbitrary coefficient of friction so the numbers don't really matter, but I am curious whether more than the y-axis direction changes when something is dropped on a rotating disc.
Right now an object hits the disc and immediately bounces back up: it's y-direction is reversed and decreased due to friction, but would the x- or z-direction also change considering the disc is rotating and may impart some angular momentum? I want to stress the object collides with the disc for a monumentally small amount of time, it might as well be 0.
