Angular momentum newbie question

Click For Summary
The discussion centers on the conservation of angular momentum and the relationship between radius and velocity in circular motion. When a particle moves from a larger radius to a smaller one, its angular velocity increases, which requires an increase in tangential velocity to maintain angular momentum, necessitating an energy input. The participants clarify that while angular velocity increases, the linear (tangential) velocity remains consistent unless a force is applied, which alters the trajectory and speed. They emphasize that pulling an object inward requires work, leading to an increase in both linear and angular momentum. The conversation highlights the complexities of angular momentum conservation and the forces involved in changing the radius of motion.

I'm afraid I missunderstood your procedure, as I explained to Doc Al above. Kindly stop quoting my posts inappropriately.
