Introduction

The PASCO CI-6689A Chaos Accessory is designed
for use with the PASCO CI-6538 Rotary Motion Sensor
(RMS) or the PASCO CI-6625 Rotary Motion Sensor for
ULI. It consists of an aluminum disk (identical to the
one provided with the PASCO CI-6691 Mini-Rotational
Accessory), a mass which attaches to the edge of the
disk to form a physical pendulum, two springs for put­ting tension in the thread, and an adjustable-gap mag­net which attaches to the side of the RMS to provide
variable magnetic damping.

Please refer to the instruction manual supplied with the
Rotary Motion Sensor for a detailed description of ex­periments using the Chaos Accessory.

Chaos Experiment

The purpose is to examine the different modes of oscilla­tion of a damped driven physical pendulum caused by
varying the driving amplitude, driving frequency, mag­netic damping, and initial conditions.

Additional Equipment Required

• IDS Mount Accessory (CI-6692)
A mounting bracket for mounting the RMS to the

PASCO Introductory Dynamics System tracks (1.2
meter ME-9435A or 2.2 meter ME-9458).
