SUMMARY
The discussion clarifies the distinction between point mass objects and extended objects in physics. A point mass is defined solely by its position in space, lacking any physical dimensions, while an extended object possesses a definite, finite size and shape. The configuration of a point particle is characterized by its position, whereas a rigid extended object is described by the position of its center of mass and its orientation. Understanding these concepts is crucial for grasping the degrees of freedom associated with different types of physical bodies.
