Step
1.
These initial conditions show a fast ball.
What happens to the fastball with
0.00 release spot and a 0 release angle?
Step 2.
Repeat Step 1
but this time make the ball curve by making it Spin 500 rpm.
Will the umpire call this a ball or a strike? Why?
Step 3.
Now increase the Spin
to 1200 rpm. Is it a ball or a strike?
Step 4.
Complete the chart
below using CurveBall setting the Spin to 1200 rpm for the curve ball.
Record the distance from the center of the plate that is displayed on the screen.
Above
the plate should be positive distances, and below the plate should be
negative distances. Record the distances for the given release spot.
Repeat this for a Left Hander and record your results.

Using four different
colored pens graph the information on the graph provided in the worksheet.
In each of the graphs the Release Spot will be x.
Graph #1--Use color
# 1 and Curveball -Left hander as y.
Graph #2--Use color
#2 and Fastball - Left hander as y.
Graph #3--Use color
#3 and Curveball - Right hander as y.
Graph #4--Use color
#4 and Fastball - Right hander as y.
