Types of movement
Movement refers to the change in position of a part or the whole of an animate or inanimate body. The types of movement vary according to the nature of the object being observed.
In addition, the trajectory must always be taken into account in relation to the elapsed time and the initial reference position.
Types of movement in physics
In physics, the movements of bodies under the action of forces is studied by mechanical science.
In this sense, the types of movement in mechanics are divided into 3 large areas of study according to the nature of the objects, being them:
- Relativistic mechanics, mechanics of celestial movements or celestial mechanics: study the types of movements of the stars and celestial objects taking into consideration Albert Einstein's Theory of Relativity.
- Classical mechanics or Newtonian mechanics: defines the types of movements of ordinary objects on Earth, that is, those whose movement is less than the speed of light. It is based on Newton's laws with the variables of gravity, mass, and motion.
- Quantum mechanics or quantum field theory: study the types of motion of matter on the atomic and subatomic scale.
On the other hand, kinematics (within physics and mechanics) studies the motion of objects by defining their magnitudes of position, velocity and acceleration. Taking as variables the trajectory and time, the following types of movement are distinguished:
- Uniform rectilinear motion (M.R.U.): object moves in only one direction, for a certain distance with constant speed and time.
- Accelerated rectilinear motion: it differs from the previous one by the constant acceleration of the object.
- Uniformly varied rectilinear motion: the variation of speed and time is constant in the object.
- Curvilinear movement: this movement includes parabolic, elliptical, vibratory, oscillatory and circular movements.
Types of Earth movements
The types of motion of the Earth, like a celestial body, is studied by relativistic mechanics. In general, there are 2 types of movements of the Earth:
- Rotation: continuous movement of the Earth on itself that defines day and night.
- Translation: elliptical movement around the sun that defines the seasons of the year.
See also Rotational and translational movement.
Types of movement of tectonic plates
On the land surface of our planet Earth there are other types of movements, such as those generated by tectonic plates. Mountain ranges and basins are the visible edges of the plates where forces that cause tectonic, seismic and volcanic activities are concentrated.
The Andes Mountains, for example, known as the Pacific Ring of Fire or Pacific Ring of Fire, contains the most important subduction zones, that is, it is the place on Earth where the greatest seismic and volcanic activity is concentrated. .
The types of movements of tectonic plates can be divided into 3 types:
- convergent movements: collision of tectonic plates.
- divergent movements: separation of tectonic plates.
- transformative movements: joint sliding of tectonic plates.
See also Tectonic plates.
Types of social movements
Social movements are informal groups that seek to generate some type of social change.
In general, social movements are classified into 4 types that differ from each other due to their identity, adversary and social dimension:
- Reform movements: those that demand changes from within, include strategies of institutionalization and cooperation with them, such as student movements.
- Revolutionary movements: they ask for changes from outside, including confrontations for the construction of new spaces of power, such as, for example, the Zapatista civil movement.
- Proactive movements: those that demand social transformations, such as feminism and ecological movements.
- Reactive movements: they refer to resistance movements, such as indigenous movements.
Types of migratory movements
Throughout history, there have been several human migrations that have generated impacts and changes in societies. These are defined by the type of migration according to the geographical dimension, the motivation, the temporality and the legal context.
Among them we can mention:
- Forced migrations: we have as an example the situation of refugees who migrate to other countries fleeing from wars in their own countries.
- Voluntary migrations: those whose motivation is the search for a better quality of life or work, for example.
- Internal migrations: local or community migrations refer, for example, to evictions by the authorities and national ones, such as migrations from the countryside to the city.
- External or transnational migrations: migrations to another country seeking, for example, better study or work opportunities.
- Definitive migrations: whose actors do not plan to return to their country or city of origin.
- Temporary migrations: where migration has a defined objective for a specific period of time, such as student exchanges.
- Legal migrations: refer to those that follow the migration laws defined by the country, thus obtaining a legal status.
- Illegal migrations: this category includes those who are defined as illegal migrants. For not having formal or updated documentation of the place to which they migrated.
See also Migration.
Types of literary movements
Literary movements are a set of works that share certain literary characteristics that generally span a particular period.
In this sense, the types of literary movements, also called literary currents, are exposed as follows in chronological order:
- Greek literature: 4th century BC to 4th AD.
- Medieval or Middle Ages literature: 5th to 14th century.
- Renaissance: 15th century until the end of the 16th century.
- Baroque: 17th century.
- Neoclassicism: 18th century.
- Romanticism: 18th to 19th century.
- Realism: second half of the 19th century.
- Modernism: end of the 19th century to the beginning of the 20th century.
- Vanguardism: 20th century.
- Contemporary literature: second half of the 20th century to the present.
See also Literary Currents.
Types of body movements
Body movements help us with day-to-day tasks and through planned repetitions we can also improve our physical well-being, which, in turn, will improve our mental health.
In physical education, the types of body movements, generally joint, are classified into the following types:
- abduction or withdrawal,
- adduction or approach,
- internal and external rotation,
- pronation and
- lateral flexion.
See also Physical exercise.
Types of camera movement
In audiovisual disciplines such as cinema, for example, the types of camera movement are important to express more accurately or creatively what is intended to be narrated.
Along with the shots, there are different types of camera movements that are classified as physical or optical.
Among the types of physical movements we can name:
- Panning movements: these include rotating the camera on its own axis, horizontally, vertically, or tilt, oblique, circular or 360 ° and sweep.
- Movements travel: camera varies the position of its axis, moving in a three-dimensional space. Among them are the accompaniment, the approach, the distance, the circular, the horizontal, the vertical, the oblique and the traveling zoom.
Optical movements are divided into:
- Movements zoom: include zoom in, zoom out, steady cam and crane.
- Focus movements: we can find those based on distance, arbitrary focus, depth of field movements and perspective manipulation movements.
