Classical mechanics:
Description of Classical Mechanics:
Classical mechanics is the study of the motion of bodies including the case in which bodies remain at rest in according with the general principles first enunciated by Sir Isaac Newton in his Philosophiae Naturalis Principia Mathematica (1687), commonly known as Principia. Classical mechanics was the first branch of Physics to be discovered, and is the foundation upon which all other branches of Physics are built. Moreover, classical mechanics has many important applications in other areas of science, such as Astronomy (e.g., celestial mechanics), Chemistry (e.g., the dynamics of molecular collisions), Geology (e.g., the propagation of seismic waves, generated by earthquakes, through the Earth's crust), and Engineering (e.g., the equilibrium and stability of structures). Classical mechanics is also of great significance outside the realm of science. After all, the sequence of events leading to the discovery of classical mechanics--starting with the ground-breaking work of Copernicus, continuing with the researches of Galileo, Kepler, and Descartes, and culminating in the monumental achievements of Newton--involved the complete overthrow of the Aristotelian picture of the Universe, which had previously prevailed for more than a millennium, and its replacement by a recognizably modern picture in which humankind no longer played a privileged role.Classical mechanics is also called Newtonian mechanics because nearly the entire study builds on the work of Isaac Newton.
Classical mechanics describes motion of macroscopic objects, from projectiles to parts of machinery, as well as astronomical objects, like spacecraft, planets, stars, and galaxies. Besides this, there are many specializations within the subject deal with solids, liquids and gases and other specific sub-topics. Classical mechanics also provides accurate results as long as the study is restricted to large objects and the speeds involved do not approach the speed of light. When the objects become sufficiently small, it becomes necessary to introduce the other major sub-field of mechanics, quantum mechanics, which reconciles the macroscopic laws of physics with the atomic nature of matter and handles the wave–particle duality of atoms and molecules. When both quantum and classical mechanics cannot apply, such as at the quantum level with high speeds, quantum field theory (QFT) becomes applicable.
The World View of Classical Mechanics is also an example of classical mechanics in our daily life
