A. Baseball Assessment

The graph below shows 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.

After the ball is thrown, what is the contact force on the ball?

In Question 1, Points A, B, and C represent three balls thrown at the same 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.

In Question 1, Points A, B, and C represent three balls thrown at the same initial speed, but under different wind conditions.

If all three balls (A, B, and C) had equal amounts of KE when they left the pitcher's hand, would they all have the same amount of KE when they reach home plate?

Explain your answer choice from question 3. Use evidence from questions 1 and 2.

Use the words kinetic energy, transfer, and air resistance.

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.

Predict how fast a player could swing a bat with a mass of 779 grams.

Which speed below is the correct prediction of the speed of the bat?

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?

Explain the cause and effect using the words forces, energy transfer, and kinetic energy.

What has a bigger effect on the kinetic energy of the bat and the ball?

(Choose the best claim.)

In question 10 you answered the following question:

"What has a bigger effect on the kinetic energy of the bat and the ball?"

Identify data from the chart in question 9 that proves your claim to be true.

Some baseball stadiums are located at a much higher altitude than most stadiums.

Coors Field in Denver, Colorado, is the home stadium for the Colorado Rockies. 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.

How would you expect the data to be different if there were fewer air particles?

Use the data to explain your answer to Question 11.
