Baseball Bat Debate: Wood
Vs. Aluminum
By: Christopher Merone, Michael
Indelicato, and Richard Centra
Hypothesis:

We, as a group, hypothesized that the
Aluminum baseball bat will be more
advantageous in the game of baseball
rather than a wooden baseball bat.
Compare and Contrast: Wooden
Bat and an Aluminum Bat:

Aluminum:
 Hollow core
 Doesn’t break, might
dent.
 Easier to swing
 Less sting on player’s
hands when contact is
made.
 Bat weight is evenly
distributed.

Wood:
Plastic core
Will break, which affects
the rate of the game.
Harder to swing.
More maintenance such
as: applying pine tar or
tape in order for the
player to get a clean
grip.
More sting.
Top heavy.

Methods and Observations:

We used trial and error and marked the “sweet spots” of
the bat tape in order to see where the ball landed
throughout the baseball bat.
You may be wondering what the “sweet spot” on the ball
really is: The spot on the bat that produces the least
amount of sting on the player’s hands, when contact is
made.
Besides testing which bat would be more advantageous, we
tested to see if hitting the ball on the “sweet spots,” would
affect the rate at which the ball travels.
Trampoline affect: When a baseball makes contact with an
aluminum bat, the bat compresses like a spring at the point
of contact. The baseball is not compressed and does not
lose energy to friction forces. The trampoline effect returns
the energy back to the ball.

Conclusion:
After much testing and note taking, we
have proven our hypothesis to be correct,
that an aluminum baseball bat, is in fact,
more advantageous.
 We enjoyed performing our experiment,
and we hope this project was a help to
many player’s who want to fulfill their task
of playing baseball, on the highest of
levels.
