Specification of a material points system

To assign a systan state means that one can describe a system s configuration (i.e., to know the position of all the elanents) at the initial instance of lime, being able to calculate it at any other time. 

This implies that for the determination r(t +dt) one needs to know r(t) and v(t), i.e., six numbers in total. If a system consists of N particles, the number of parameters 

For the assignment of a system state in modem physics, a so-called configuration space is introduced. The dimensionality of this space is the number of parameters defining the state of a system at a point of time, the change of this state being defined by the set of points, i.e., the line. The element of the configuration space volume dr in analogy with a
