Moment of Inertia
Given two pool cues with the following characteristics:
1) the same weight (mass)
2) each having its own moderately uniform density
3) two significantly different lengths, say 58" and 68"
The longer cue will have a higher moment of inertia about the pivot point constructed within the bridge hand. That higher MOI will make it take a little more effort to rotate the cue about the bridge hand. The effect will feel like the cue is slightly more stable about that rotation axis.
Think of this exaggerated example to help clarify. You have a 20 pound dumbbell. Ignore the mass of the handle. Pick it up and let it hang straight down from your shoulder. Now spin it clockwise and counterclockwise. Should be pretty easy.
Try doing that if the handle was a 3 feet long massless handle. It would be far more difficult even though the weight would still be 20 pounds.
There can be downsides to a long cue though I guess. Convenience and whacking things inadvertently come to mind. Still, I think cues will lengthen over time. We will see.
Research moment of inertia to learn more. Hope this helps.
