The Baseball and Air Worksheet

Explanation:

Step 2.

Using a ruler, measure the distance between the red ball of the probe and the center of the ball. How fast is the airstream moving around the ball at this distance?

 

Distance ___________mm. Speed of the airstream ______________km/hr.

 

Step 3.

By moving only the left slider in the Probe Control Panel move the probe to the right of the ball and take five readings of distance and speed. Record these in the chart below. Repeat this for five readings to the left of the ball.

Right Side Distance (x)
Right Side Speed (y)
Left Side Distance (x)
Left Side Speed (y) 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Step 4.

Using two different colored pens, graph the information from the chart on the graph provided. Graph #1 will be the right side of the ball, and graph #2 will be the left side.

Conclusions:

  1. What happens to the airstream as the probe is moved farther from the center of the ball? 

      

  2. Why do you think this happens? 

     

  3. What happens if you change the speed of the ball?

     

  4. Does this change what you discovered in Question 1?

      

  5. Does your result change if you throw a curveball? a screwball?

     

  6. Examine your graphs. What kind of relationship exists between an airstream's distance from the ball and the speed of the airstream?

     

  7. Write an equation for one of your graphs.

     

  8. Why is this the correct equation?
