Document Summary

Rotation correspond to the motion of an object about a given axis. The proper study of this type of motion requires several elements: de ne a good reference system. In the gure, z axis coincides with the rotation axis: de ne angular variables that simplify the math for describing the position of the object respect the ref- erence system. A rigid body is a particle system where the distances between all of them remain xed at all times. In other words, the body does not suffer deformations. A rigid body is sometimes called also solid. Because we can study the motion of the complete body paying at- tention to a single point of the object, and then refer the rest of the body to that point. A very useful reference system selection is one where one of the axis coincides with the rotation axis.
