This book contains graphs showing the motion of a tennis ball, cricket ball, racquetball, lacrosse ball, softball, field hockey ball, street hockey balls (high and low density), and Swedish hockey puck-handling ball as they fly through the air. Some graphs also show the balls hitting a wall and bouncing back. The graphs and data contained in this book can be used by teachers and parents to supplement traditional lesson plans. Bonus Material: For comparison and contrast, a selection of balls from Volume 3 are provided. Graphs show data from a basketball, soccer ball, volleyball, dodge ball, 3 baseballs (official, safety, and plastic), 3 golf balls (official, foam and plastic), a ping pong ball, and a plastic apple as they fly through the air. Several of these graphs also show the trajectory of balls bouncing off a wall.
