Classical mechanics is one of the two major sub-fields of mechanics. It is concerned with the set of physical laws describing the motion of bodies under the action of a system of courses. It is the study of the motion of bodies. Classical mechanics is one of the oldest and largest subjects in science, engineering and technology.
Classical mechanics describes the motion of macroscopic objects. This can range from projectiles, parts of machinery as well as astronomical objects. Classical mechanics also deals with gases, liquids and solids within its subtopics. Classical mechanics does a very good job at describing the results of large objects; however when objects get small it is necessary to introduce sub fields of mechanics, such as quantum mechanics.
The term classical mechanics was named in the earliest 20th century. It was used to describe the system of physics begun by Isaac Newton and contemporary 17th century natural philosophers. The initial development if classical mechanics is referred to as Newtonian mechanics. The developments of analytical mechanics in the 18th and 19th century were also huge in the creation of quantum mechanics.
