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 put-

ting tension in the thread, and an adjustable-gap mag-

net 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 ex-

periments using the Chaos Accessory.

Chaos Experiment

The purpose is to examine the different modes of oscilla-

tion of a damped driven physical pendulum caused by

varying the driving amplitude, driving frequency, mag-

netic 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).
