During purely translational motion (motion with no rotation), all points on a rigid body move with the same velocity.

By selecting the center of gravity as the reference point for a rigid body, the gravity forces will not cause the body to rotate, which means weight of the body can be considered to be concentrated at the center of mass.

In other words, the distance between any two given points of a rigid body remains constant in time regardless of external forces exerted on it.

In a rigid body vortex flow of a fluid with constant density, the dynamic pressure is proportional to the square of the distance r from the axis.

A rigid body is called chiral if its mirror image is different in that sense, i.e., if it has either no symmetry or its symmetry group contains only proper rotations.

An environmental psychologist told me, If you're sitting in a hard chair on a rigid surface, you'll be more rigid.
