Product InformationAnother great demonstration from our favorite &"swinger,&" Bruce Yeany.A bar pendulum and a steel bob pendulum, both the same length, hang side by side. When given the same amount of energy the two pendulums swing with different periods. Why does this occur? Is there a way to synchronize the pendulums? The answers are in this demonstration and accompanying teacher’s guide. Grades 10-12. Tell a Friend about this item
