This book contains graphs showing the motion of hockey balls and pucks as they move across a variety of surfaces. Data are presented for a field hockey ball, two street hockey balls (high density and low density), an official ice hockey puck, a practice ice hockey puck, and an air hockey table puck. Surfaces include carpet, wood, ice, synthetic ice, and air table with and without the friction-reducing effects of air. Additional coordinated graphs show the impact forces associated with movement over a flat surface, as well as the forces required to push a puck continuously for a specific distance. Graphs of collisions between moving objects (balls/pucks) and a wood sideboard are also included. These data can be used for lesson plans by teachers and parents.
