The length of time it takes a ball to swing back and forth one time to return to its starting position is dependent on the length of the pendulum, not the mass of the ball. A longer pendulum will take longer to complete one cycle than a shorter pendulum. The lengths of the pendula in this demonstration are all different and were calculated so that in about 2:40, the balls all return to the same position at the same time.<\/span><\/p>\n<div class=\"youtube\" style=\"background-color: #dcdcdc;padding: 2px\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>This is a large-scale demonstration of the interaction between period and pendulum length, using 16 bowling balls hung from a wooden frame.
