Webt. e. In analytical mechanics, generalized coordinates are a set of parameters used to represent the state of a system in a configuration space. These parameters must uniquely define the configuration of the system relative to a reference state. [1] The generalized velocities are the time derivatives of the generalized coordinates of the system.
