This book contains graphs showing the motion of baseballs, basketballs, soccer balls, volleyballs, dodge balls, golf balls, tennis balls, ping pong balls, and toy balls as they fall and bounce. Balls are bounced on different surfaces, including wood, linoleum, carpet, concrete, foam, and a force plate. Special features include the comparison of an official baseball with a safety baseball and a plastic baseball, and the comparison of an official golf ball with a foam golf ball and a plastic golf ball. Data also compare the motion of a basketball, soccer ball, and volley ball with different inflation pressures. The graphs and data contained in this book can be used by teachers and parents to supplement traditional lesson plans.
