I had to do some research on this, since I'm more
of a football fan,myself... ;-) It looks like it
would be very difficult to set up a really good
experiment comparing the two, since the speed of
the bat depends on a lot of factors that are
difficult to control in an experiment.
what I've learned about the advantages of the two
types of bats:
Aluminum bats are lighter, which
makes it easier to swing faster and also makes it
easier to control the bat. This can even give the
batter a chance to wait longer before swinging and
make some last-second adjustments to a pitch.
Wooden bats, on the other hand, are
heavier,which makes it harder to achieve the same
bat speed and harder to control the motion of the
bat. The trade-off is that the wooden bat's
collision with the ball is more effective than the
aluminum bat's collision. A wooden bat moving at
the same speed as an aluminum bat will make the
ball go farther, since the wooden back has less
"recoil"and also more momentum.
Even if the
bats had the same overall weight,the weight of the
wooden mass is mainly in the barrel, while the
weight of the aluminum bat is more evenly
distributed over the whole bat. The weight of the
bat in the region where the ball is hit would
still be much higher in the case of a wooden bat,
so it would still provide a more effective
hit.What that all means in the end is that what
bat is best to use is pretty much a matter of
personal preference. Aluminum bats are easier to
control and to swing faster, but wooden bats have
the potential to hit the ball more effectively and
thus make it go farther. In an experiment with
the bats moving at the exact same speed, the
wooden bat should win,but in a real-world
situation, the increased control for an aluminum
bat can allow the batter to make a "cleaner" hit
and send the ball farther.Hope that helps out!
Good luck in the science fair!
