iPhone wheel (of fortune) rotation momentum

I'm having difficulties adding momentum to my spinning wheel. I have this wheel (something like this) and I'm rotating it around it's center by using a single touch event. No problems here, but when the touch (aka drag) ends; I want the wheel to…

Angular Momentum Transfer equations

Does anyone have any good references for equations which can be implemented relatively easily for how to compute the transfer of angular momentum between two rigid bodies? I've been searching for this sort of thing for a while, and I haven't found…

Interpolate x, y, z coordinates on a sphere using points from two spin vectors?

I want to plot 3D points in real time that lie upon the surface of a unit sphere (r = 1). There are two spin vectors at work here. One vector rotates around the Y axis, it's X and Z values are calculated using the cos() and sin() of a circle that…

Obtaining momentum quaternion from two quaternions and timestep

I have a quaternion which holds the rotation of an object. During the frame I modify it and obtain a new quaternion. I can calculate a quaternion that rotates from 'previous frame' to 'current frame'. I cannot figure out, however, how to 'divide by…

Angular momentum about different points

From what I have gathered, angular momentum in a system can be calculated about any point. However, I am having trouble grasping this, and below I suggest an imaginary situation where I try to apply this. Imagine a rod of mass %m% and length…
