Easton Bats V.S. The Combat

Question

Which kind of baseball bat will hit a baseball farthest… a Combat which is all composite or an Easton baseball bat which is half composite half alloy?

Hypothesis

I predict that the Combat will hit the baseball farther than an Easton baseball bat based on the fact that it is all composite and I don’t think weight will be the deciding factor.

Abstract

My project is all about the effectiveness of baseball bats. The two bats I will test the effectiveness of are a Combat and an Easton baseball bat.

Materials List

1. A 200 foot tape measure2. A Combat3. An Easton bat4. A baseball tee5. 3 baseballs

Variables

• The Independent Variable: It is the type of bat.

• The Dependent Variable: It is the amount of feet the ball travels.

• The Control Variable: It is the number of baseballs hit, the number of people that use each bat, the place they hit the ball from, and the type of measurement used( inches, feet, yards).

Procedures

1. The first step in my experiment was to gather all of my materials.

2. Then I got each test subject to hit 3 baseballs off of a tee with the Combat first.

3. Then after I had measured the length of each hit, the test subject would switch bats and hit 3 baseballs with the Easton.

4. After each hit I would measure the length the ball traveled just like before.

5. Then the next test subject would do the same thing as the person before them.

Results

I claim that the half and half Easton bat hits the ball farther than the all composite Combat. Evidence shows that this is true because the half and half bat is lighter and will flex more than the all composite bat.

Conclusion

My hypothesis is incorrect. The lighter half composite half alloy bat hit the ball farther than a one ounce all composite bat. Even though the Combat has a bigger sweet spot and is all composite the half and half Easton bat which was lighter proved to hit the ball farther with most people. In conclusion the Easton baseball bat hit the ball farther because it is lighter and even though it is not all composite it still has a little bit of composite in it. Also the 2 piece bat flexes creating a whip like affect when it hits the baseball.

Application

You would need to know if an all composite bat hits a baseball farther than a half and half bat because if you are playing travel baseball and need to know which bat hits a ball farther this helps you decide.
