Real World Physics Problems published a simple explantion of gyroscope physics here and their principal drawing is as follows:
The explanation involves differentiating particles in the top half of the spinning wheel from those in the bottom half and treating them as Newtonian objects.
The Newtonian object is the spinning wheel-shaft combination. It is not comprised of smaller ‘objects’ because Newtonian objects have to have space between the shapes (as defined by Bill Gaede in the previous post) in which to observe motion between them.
Newtonian forces act on objects which have to be able to move independently of each other, otherwise if they can’t you, as another object by the way, won’t see any motion between the other objects.
And I don’t understand how gyroscopes work, and certainly don’t understand gravity either but I’m working on it.
And do ignore explanations by those afflicted with mathematitus.
