What's better than a pendulum for studying motion and periods? A double pendulum! Young physical scientists use an interactive to explore pendulum motion—times two. The resource boasts a host of parameters to change and a running graph...

Add some zing to your swing! Explore pendulum motion through an engaging interactive. Physical science scholars specify the pendulum's mass, rod length, and starting angle before they observe the resulting angle graph.

What makes a swing go back and forth like a pendulum rather than going all the way around? Scholars use the simulation to explore pendulums and how they work. They vary the weight, length of the rope, and even gravity in various trials.
