In the Tromsø Science Center they have this model, a set of pendulums in which the second pendulum travels twice the speed of the first, the third three times, and so on. I posted a flash program of this pendulum trick earlier that allows to you experiment with the number of balls. What is the shape of the frame that the pendulums attach to? How does length of the pendulum affect the time it takes to complete one swing, and how must the lengths change to have a linear progression of time change from one pendulum to the next?
