The study of the forces and movements of bodies is governed by different laws and principles depending on the field in which we move.

Classical mechanics is based on the study of motion and forces on bodies in inertial systems. It is made up of areas of study that range from the\u00a0rigid solid mechanics<\/strong>\u00a0(non-deformable solids) and \u00a0mechanics of continuous media<\/strong>\u00a0(such as gases and liquids).<\/p>\n The basis of classical mechanics is the Newton's Laws<\/a>This is why it is known as Newtonian mechanics. It is divided into: kinematics, the study of movement without studying the causes that give rise to it; statics, which deals with the equilibrium between forces; and dynamics, which is the study of movement by looking at its origins, the forces.<\/p>\n Within the mechanics of continuous media we would distinguish the fluid mechanics<\/a>which comprises a set of partial theories such as hydraulics, hydrostatics and hydrodynamics. <\/p>\n The relativistic mechanics or theory of relativity developed by Einstein comprises:<\/p>\n Relativistic mechanics is much more similar to classical mechanics from a formal point of view than for example quantum mechanics. In velocities and in the inertial environment of the Earth, relativistic and classical mechanics give almost identical results. <\/p>\n<\/div>\n The\u00a0quantum mechanics<\/strong>\u00a0is the one that deals with physics at the atomic level and is where concepts such as uncertainty, unknown in classical physics, are introduced. Max Planck is known as the creator of quantum mechanics. The name quantum comes from \"quanta\". It refers to the way in which energy is absorbed or emitted. Energy is emitted or absorbed in the form of quanta, not emitted or absorbed continuously.

From this observer, in the inertial system, Newton's laws are fulfilled. The relative motions on the Earth, from a stationary observer, will be in an inertial system.<\/p>\n A non-inertial system is a system where Newton's laws are not fulfilled. For example, a body moving with acceleration will not be an inertial system. Fictitious forces will be necessary to solve these problems.<\/p>\n Mechanics is the branch of physics that studies and analyses the motion and rest of bodies, and their evolution over time, under the action of forces. Mechanics is a science belonging to physics, since the phenomena it studies are physical, and is therefore related to mathematics. However, it can also be related to engineering.
