Question

generalized coordination

Answer 1

In analytical mechanics, specifically the study of the rigid body dynamics of multibody systems, the term generalized coordinatesrefers to the parameters that describe the configuration of the system relative to some reference configuration. 

Answer 2

In analytical mechanics, specifically the study of the rigid body dynamics of multibody systems, the term generalized coordinatesrefers to the parameters that describe the configuration of the system relative to some reference configuration. These parameters must uniquely define the configuration of the system relative to the reference configuration.[1] This is done assuming that this can be done with a single chart. The generalized velocities are the time derivativesof the generalized coordinates of the system.

An example of a generalized coordinate is the angle that locates a point moving on a circle. The adjective "generalized" distinguishes these parameters from the traditional use of the term coordinate to refer to Cartesian coordinates: for example, describing the location of the point on the circle using x and y coordinates.
