Meaning of Mechanics (What is, Concept and Definition)

What is Mechanics:

Mechanics is the science that studies the movement of bodies under the action of the participating forces.

In physics, theoretical studies on the mechanical behavior of objects such as, for example, in classical mechanics, relativistic mechanics and quantum mechanics is important to understand the dynamics of the world around us.

See also Quantum mechanics.

The application of knowledge about mechanics has helped in the construction of structures with mechanical movements facilitating the life of man.These studies are covered, for example, in mechanical engineering and in automotive mechanics .

Both the study and the application of mechanics must know the principles of the mechanical energy as the force that will drive a mechanism.

Mechanical solidarity, on the other hand, is associated with society s whose division of labor is the same for everyone contrary to organic solidarity.

See also mechanical and organic solidarity.

Branches of mechanics

The principles of mechanics apply to the following areas or subdisciplines:

• Relativistic mechanics, celestial movements mechanics or celestial mechanics: study the behaviors and displacements of the stars and celestial objects such as planets, their moons and the sun that move at great speeds in space and time.It is related to the Theory of Relativity of physicist Albert Einstein.
• Classical mechanics or mechanics of ordinary Earth objects: it focuses on objects whose speed of movement is less than the speed of light applied to almost all the bodies that exist on Earth.Classical mechanics is based on mechanics Newtonian where gravity is introduced along with mass and movement as concepts central areas.
• Quantum mechanics or quantum field theory: it focuses on phenomena at the microscopic level, that is, it analyzes the behaviors and electromagnetic radiation of matter in a Atomic and subatomic scale.

Classification of mechanics according to Kirchhoff

The German physicist Gustav Robert Kirchhoff (1824-1887) I classify mechanics into two general groups: kinematic mechanics and dynamic mechanics.

• cinematic mechanics or also called movement geometry studies the movement of physical bodies as geometric bodies without taking into account the relations with the laws or their causes.The study of kinematics involves two types of objects:

-the rigid solids: objects whose molecules (elementary particles of a mass) maintain a constant distance despite the force exerted.

-the elastic solids: bodies that change their internal structure by applying more or less force on the.

• The dynamic mechanics focuses on the movement of bodies considering the laws and their causes.They are subdivided into:

-the kinematics: the study focuses on animated objects considering the force of acceleration.

-the static or science of balance: study the uniform movement and rectilineo of the bodies at rest or animated.
