Let's work this through... I am not sure what level of physics you are taking.
Please write how you understand (from your class) what conservation of momentum is (this could either be a description or a mathematical function).
Then we can talk it through.
Thankyou for your reply. I'm sorry it took so long for my response, but I don't have a computer and have to go to the library once a week.
I have a pretty good understanding of conservation of angular momentum in that the rotational velocity times the moment of inertia (distance of mass from center) equals the momentum. I understand that moving the mass away from the center must slow the velocity, as a ballet dancer doing a pirouette. But the book I'm reading (Isaac Azimov) doesn't mention the stabilizing of the axis with the increasing moment of inertia. I think this is an important concept with many applications, and I'm struggling to understand it. I can see that a bicycle becomes stable as it moves, but I don't know why.
I'd appreciate it if you can help me with this.
