==Description==
A '''trampoline''' is a device consisting of a piece of taut, strong [[fabric]] stretched over a steel frame using many coiled springs. People bounce on trampolines for recreational and [[competitive]] [[purposes]].
The fabric that users bounce on (commonly known as the 'bounce mat' or 'trampoline bed') is not elastic in itself; the elasticity is provided by the springs that connect it to the frame, which store [[potential]] [[energy]].
Trampolining is an individual sport of acrobatic movements performed after rebounding into the air from the trampoline. As a [[competitive]] sport, it was included in the Pan-American Games for the first time in 1955, and a world championship was established in 1964; competitors are scored on [[difficulty]], execution, and [[form]].
