PhysicsFun 723 - The Pendulum Snake
Pendulum Snake - one of my favorite exhibits: ten swinging spheres, the first has a frequency of 15 swings per 30 seconds, the second has 16 in the same time, the third has 17, up to the tenth with 24 swings per 30 seconds. If released at the same time and height the amazing patterns result as each independent pendulum goes in and out of phase with the rest. Note that for a pendulum the frequency of oscillation depends on the square root of its length. 🌟 With special thanks to the Exploratorium!
