# Conservation of Angular Momentum

## Introduction

In your study of linear momentum, you learned that, in the absence of an unbalanced external force, the momentum of a system remains constant. In this experiment, you will examine how the angular momentum of a rotating system responds to changes in the moment of inertia, I.

## Objectives

In this experiment, you will

• Collect angle vs. time and angular velocity vs. time data for rotating systems.
• Analyze the θ-t and ω-t graphs both before and after changes in the moment of inertia.
• Determine the effect of changes in the moment of inertia on the angular momentum of the system.

## Sensors and Equipment

This experiment features the following Vernier sensors and equipment.

You may also need an interface and software for data collection. What do I need for data collection?
