## C8-01: GIANT PENDULUM

• ID Code: C8-01
• Purpose: Demonstrates conservation of energy
• Description: The instructor backs up against the ladder/plywood backdrop, holds the pendulum bob up to his or her chin, and releases it. Because of conservation of energy the bob will swing across the stage and return to its original position adjacent to the instructor's chin, but without hitting his or her chin. Despite the wariness of the students, the pendulum bob cannot rise to a height greater than its original height, and the instructor is safe. Demo requires a minimum of 24 hours notice to prepare mounting cable. E-mail Lecture-Demonstration the day before to ensure that cable is ready.
