This book provides students and scholars with a fail-safe guide to the key concepts in the field of Sport & Exercise Science. Intelligently cross-referenced entries provide a sound map of the multi-disciplinary demands of sport related courses including physical and biological sciences, social science and education. The entries use clear definitions, examples, and suggestions for further reading to explore each discipline.
A projectile is an object that is moving through the air unassisted with only gravity and air resistance acting upon it. There are numerous examples of projectiles in sport including sports objects such as a golf ball, basketball, tennis ball, rugby ball, football, shuttlecock, discus, hammer and frisbee, and sports performers such as long jumpers, high jumpers, gymnasts, figure skaters, ski-jumpers and sky divers. Projectile motion refers to the type of motion experienced by projectiles travelling through air and, ignoring air resistance, is a special example of linear Kinematics where we know what changes in velocity and acceleration there will be once an object or body is released. Ignoring air resistance is okay in a number of sports examples (e.g. shot putt) where the ...
