This volume contains graphs of the motion of two oblong balls, an American football and a rugby ball. Graphs show the orientation of these balls as they are turned in various directions along different axes. Other graphs show the motion of these two balls as they spin and rock from side to side on a flat surface, and as they roll on flat and inclined surfaces. Additional graphs show the balls falling, bouncing, and flying through the air. Coordinated graphs provide analysis of all 3 dimensions during a subset of these motions; several pairs of graphs provide data on both the forces and the resulting motions of the balls. The graphs and data contained in this book can be used by teachers and parents to supplement traditional lesson plans.
