D1-65: YO-YO

• ID Code: D1-65
• Purpose: Illustrate transformation between various forms of energy and to perform yo-yo tricks.
• Description: Simply holding the end of the string to allow the yo-yo to unwind and wind back up again illustrates transformation between gravitational potential energy and rotational kinetic energy, with a lesser amount of translational kinetic energy. See Demonstration Reference File for further information on yo-yo tricks.
