Freely demonstrate simple harmonic motion. Your lessons on this topic are no longer tied down, because of the unique construction in this pendulum.
Students view the period of an oscillating body from a different perspective than the standard string and ball.
The period of the 1" steel ball can be measured, and the distance to a focal point can be calculated to compare the demonstration to a classic pendulum.
Includes pendulum track, steel ball, and instructions.
