## Main Question or Discussion Point

Says Wikipedia: "The moment of inertia is a measure of an object's resistance to any change in its state of rotation".

Now consider a rotating mass [itex]m[/itex] that I would like to accelerate

Thanks,

Harald.

Now consider a rotating mass [itex]m[/itex] that I would like to accelerate

**along**its axis of rotation by [itex]a[/itex]. Does this count as a "change in its state of motion"? Will it resist the acceleration more that just [itex]F=m\times a[/itex]. And if yes, how much?Thanks,

Harald.
