Dynamics of Rigid Body

Translational Motion, Rotational Motion and Moment of Inertia 1. Rigid Body  A rigid body is a body made up of many particles in which the distance between particles remains constant even when forces act on it.

This means: • The shape and size of the body do not change. • Only its position or orientation changes. The motion of a rigid body can be of two types: 1. Translational motion 2. Rotational motion
