{ "item_title" : "The Science of Snow Sports", "item_author" : [" M. Schottenbauer "], "item_description" : "This book contains graphs showing the motion of scale models of a sled, toboggan, snowboard, and set of skis as they travel on inclined surfaces, consisting of snow, plastic, HDPE/plastic, and wood. Of special interest, this book features graphs of motion on curved jumps, including a simulated Alpine slope and a simulated ski jump. A series of graphs also show the forces required to move equipment over a flat surface. These data can be used for lesson plans by teachers and parents. Bonus Material: Additional graphs present comparison data for common objects as they engage in free fall and projectile motion similar to aerials. Pictures of snow compression, showing the extent to which equipment sinks into snow compared to surface area of the equipment, are also presented.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/1/49/530/066/1495300668_b.jpg", "price_data" : { "retail_price" : "20.00", "online_price" : "20.00", "our_price" : "20.00", "club_price" : "20.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
