Good read, also think axis is important.Just my opinion.
All pitches spin some way obviously. But I think axis tilt and laminar flow play a more prominent role in pitch movement than spin, Screwballs (not a step way to one side one) for example move based on seam orientation, laminar effect - no 3-9 spin is involved. If you throw curve spin but with the incorrect seam orientation/axis, it will come back over the plate (DD’s PC showed an example of this some time ago). Spin might help a curve, but it is not the main force moving it. A lot of girls can move a ball left (as a righty) without curve spin.
Cricket has a lot more research in the area of laminar flow.
As for dropballs, all balls drop eventually due to gravity, but top spin speeds up the process by adding a downward force.
WITH spin rotation.
For instance that is why there can be
a drop, a curve, and a curve drop!
