A Beuatiful Moment
From Wikipedia, "In summary, the principle of inertia is INTIMATELY linked with the principles of conservation of energy and conservation of momentum."
PLUS
From Buckeye12, "However, the major difference between aluminum and wood is the location of the moment of inertia which is much closer to the handle on an aluminum bat and more towards the barrel of a wood bat. This location allows the user of an aluminum bat to generate more bat speed than he/she could using a wood bat."
MEANS
If you drill a hole in the bottom of a wood bat and fill it with a much lighter material, such as cork, then you in effect have transfered that initial moment of inertia of a wood bat from the barrel to a location closer to the handle of a wood bat. This new location allows one to generate a FASTER bat speed which translates into a much HARDER collision and transfer of energy and momentum into the baseball.
PROOF: There really is an advantage in a CORKED BAT.
