The Physics of Classical Mechanics


Mechanics: The branch of physics dealing with the behavior of physical objects when they are subjected to forces or displacements.

Classical Mechanics: The field of mechanics that deals the physical laws that describe the motion of bodies under the action of a system of forces at every day sizes and velocities.

History

The history of Classical Mechanics is ancient going back at least to ancient Greece and Greek philosophers like Aristotle. In practice many of classical mechanics'  principles go back even further even if they were not yet formulated. Classical Mechanics became a full fledged empirical science starting with Galileo and then grew into the beginnings of physics as it is known today with men like Isaac Newton.

Limitations

Classical mechanics is limited in both speed  and sizes at which it is applicable. Whenever the size of the objects becomes extremely small quantum mechanics comes into play but on the macroscopic level quantum mechanics produces essentially the same results as classical mechanics. Further more when the speed of the objects gets extremely fast relativistic mechanics comes into play while at the speed experienced in every day life relativistic mechanics produces essentially the same results as classical mechanics. Now at larger scales of size and distance celestial mechanics come into play but this is actually just an expansion of the principles of classical mechanics to larger scales.
