Classical or Newtonian mechanics appeared on the 17th century and was very successful in describing the physics of the macroscopic world. However, in the beginning of the 20th century, experiments revealed a series of atomic and subatomic phenomena that could not be explained by the old theory. This triggered the development of Quantum mechanics.In classical mechanics a system can be described by a number of dynamic variables. The goal is to be able to calculate the exact values of these variables at any given time and determine how these values evolve as a function of time t. Once the position of a particle within an one-dimensional system is known, a series of other variables such as the velocity, acceleration, momentum, potential and kinetic energy can be calculated.
