Rigid body

In physics, a rigid body (also known as a rigid object) is a solid body in which deformation is zero or so small it can be neglected. The distance between any two given points on a rigid body remains constant in time regardless of external forces or moments exerted on it. A rigid body is usually considered as a continuous distribution of mass. In the study of special relativity, a perfectly rigid body does not exist; and objects can only be assumed to be rigid if they are not moving near the speed of light. In quantum mechanics, a rigid body is usually thought of as a collection of point masses. For instance, molecules (consisting of the point masses: electrons and nuclei) are often seen as rigid bodies (see classification of molecules as rigid rotors). (Wikipedia).

Geometric Algebra, First Course, Episode 13: Position and Attitude

In this video we begin to construct a 2D Physics simulation framework with visualization. Our first step will be to define a rigid body with position and attitude so that we can translate and rotate it in the plane, and render it as a Square (paying homage to Flatland).

The rigid body and its moment of inertia tensor

In this video we're discussing the dynamics rigid body. In particular, we motivate and compute the general form of the inertia tensor for such a system. Consider this a motivation for the use of Lie-groups and Lie-algebras. Indeed, representation that were explained in previous videos make
