____________
So, where does that force (?) come from?
There is no known force allowing the gravity directed to the ground to pull an unspun top toward the principal axis, as such is a horizontal force (orthogonal to this axis), unlike the vertical force of gravity, which cannot be the cause of this. When the top is not spinning, any horizontal force (friction) the ground that may apply opposite to the reactive centrifugal force would only cause the upper end of the top to tilt AWAY from the principal axis and toward parity with the ground.
Yet, we INFER from a spinning top that a horizontal force must exist on it towards the principal axis, as we inferred that a force must exist on the tetherball, as required by the conservation of momentum.
It is as if the cross product of top spin angular momentum and the precessional frequency CREATED the torque strength of an “anchor”. (IS THIS THE ANSWER TO THE ?)
