The Metapendulum is a combination of both the simple gravity pendulum and the spring pendulum. Both excite each another and, therefore, can be used as an example of mechanical resonance phenomena. The data of a smartphone’s accelerometer can be used to record the acceleration of the pendulum during the oscillation movement. With that, the resonance within the system can be visualized.
