ABSTRACT

In the everyday world of macroscopic objects the Newtonian laws of classical physics account extremely well for the motion of particles along defined trajectories. These laws assume that the position and velocity of a particle can be defined at every instant, from which it is possible, at least in theory, to calculate the precise position and velocity of the particle at every other instant. Classical physics further assumes that any type of motion can be supplied with any arbitrary amount of energy. Thus, for example, the range of an artillery shell is, in principle, continuously variable according to the amount of energy supplied at the initial firing.
