I don't understand the point of this (and most of the questions you've posted here). They usually start with a half-described situtation, then you ask what amounts to "what would happen if what we know about physics (or reality) wasn't true?". It's hard to tell if you are serious or just goofing around; if serious, what kind of answer are you expecting?Mt. Nixion said:Let's say that something is spinning and it spins in a certian direction. The object has rotational inertia. Now say that the object has no inertia. How many times will the object change its direction of rotation in under a second?
How can the spinning of a point which has no dimension be defined.DavidK said:A point mass would have no rotational inertia. However, spinning of a point is not very well defined.

Zero rotational inertia is a property of an object that describes its resistance to changes in rotational motion. It means that the object has no tendency to rotate or maintain its current rotation.
Zero rotational inertia and zero mass are two distinct properties. Zero mass refers to an object having no physical substance or weight, while zero rotational inertia refers to an object having no resistance to changes in rotational motion.
Yes, it is possible for an object to have zero rotational inertia. This typically occurs when the mass of an object is evenly distributed around a central axis, resulting in no net torque or rotational force.
The implications of zero rotational inertia depend on the context in which it is observed. In some cases, it may allow an object to rotate more easily or smoothly, while in other cases it may make it more difficult to control or manipulate.
Zero rotational inertia can affect the stability of an object by making it more or less susceptible to changes in rotational motion. In some cases, it may make an object more stable by evenly distributing its mass, while in other cases it may make it less stable by making it easier to rotate.
