Moment of inertia

Ages

Introduction

Summary

When a rigid body is in translational motion, the resistance to a change in its linear motion is called the mass (also called inertia). When a rigid body is in rotational motion, the resistance to a change is called the moment of inertia.

The smaller it is, the easier it is to accelerate the rotation of the object.

Here you have the moment of inertia for the most important shapes.

Goals

• To show that different positions of the axis result in different moments of inertia for the same object.
