Purpose
To demonstrate coupled oscillations in a system of two identical coupled air track gliders.

Description
Two moveable air track gliders are connected by three mini-springs to fixed end points. Pushing one of the gliders causes motion that couples back and forth between the two gliders. Giving the two gliders the same initial displacement (in phase, or out of phase) can excite two normal modes.
