1N30.50 - Impulse Demo - Elastic and Inelastic Pendulum
Set the sad-happy ball combo on the suspension and move the suspension apart until the ball swings without any lateral movement. Set the upright meter stick to a position so that when you pull back on the pendulum you come to about 62 cm. To change from an elastic to an inelastic collision just reverse the bifilar supports. The inelastic collision will not knock over the board where as the elastic collision will.
