At each level of organized baseball, there are rules in place about what type of bat and ball can be used. These rules help ensure the gameplay remains competitive, fair, and fun.
The type of bat and the type of ball are the two major factors that game organizers can control.
But there are a lot of other factors that people claim also have a big impact on gameplay that cannot be controlled, such as weather conditions, the location of the stadium, and the strength of the players.

Question 1
1.
Answer the prompts below to figure out how these factors could impact the game of baseball.
Weather Conditions and Pitch Speed
Below is a graph showing how wind speed affects pitch speed. The line on the graph shows the relationship between wind speed and pitch speed.
Points A, B, and C represent three balls thrown at the same initial speed, but under different wind conditions.
What is the contact force on the ball after the ball is thrown?

Question 2
2.
In Question 1, Points A, B, and C representthree balls thrownat thesame initial speed, but under different wind conditions.
For each ball thrown (A,B,C), show the contact forces on the ball after the ball has left the pitcher’s hand. Draw arrows to show the amount of the strength of forces on the ball.

Question 3
3.
In Question 1, Points A, B, and C representthree balls thrownat thesame initial speed, but under different wind conditions.
If all three pitches (A, B, and C) had equal amounts of Kinetic Energy when they left the pitcher's hand, would they all have the same amount of KE when they reached home plate? Why or why not?

How would you design an investigation using materials we have used in class to collect evidence for all 3 pitches to support or refute your claim for question 3?
Think about items we have used in our class and list the items you will use in your investigation.
The items and objects I will use in my investigation:
Pitcher: _______
Ball: _______
Wind: _______
We would collect measurements and data with _______
My plan for setting up and carrying out my investigation:
Controlled Variable- _______
Independent Variable-_______
Dependent Variable- _______

Representing and Explaining the Relationships between Bat Speed and Bat Mass
The data table below shows how fast a major league power hitter can swing a bat with different amounts of mass. The mass of the bat was the independent variable in this investigation, and the speed of the bat swing was the dependent variable.
Plot the data from the table on your graph.

Question 8

A batter swings a bat with the same amount of force. Why would the speed of the bat swing decrease as the mass of the bat increases?
ADD HINT: Explain the cause and effect using the words forces, energy transfer, and kinetic energy.

Question 10
10.
Some baseball stadiums (such as Coors Field in Denver, Colorado, which is the home stadium for the Colorado Rockies) are located at a much higher altitude than most stadiums. Coors Field is 5,200 feet (almost a mile) above sea level. At this higher altitude, there are fewer air particles in a given space than at lower altitudes.
Explain how you would expect the data to differ with fewer air particles? Why?
