Dynamics is a term related to movement and forces. It may be a concept in the area of physics, gives song or from psychology, in the case of group dynamic.
In the field of physics, dynamics is the science that studies motion, considering only forces as their cause. It is one of the best-founded chapters in physics and the clearest and most intuitive results when applied to rigid bodies.
Dynamics is based on Newton's laws, but with a much more complex mathematical treatment. Dynamics is also responsible for studying the movement of gases (aerodynamics) or liquids (hydrodynamics). In general, the empirical point of view, based on experimental data, predominates in this science.
Group dynamic
The concept of group dynamics is part of social psychology and is related to the forces at work in the context of a group. Any individual behaves differently when in a group, and a particular group varies its behavior depending on the context presented to it.
Group dynamics exercises are often used to improve the chemistry of different members of the same group. Some examples of dynamics that have this objective are the mirror and the present dynamics.
Today, many job interviews contain a group dynamics aspect, where an individual's ability to interact with the group is assessed. This area is increasingly valued, because people who are good at group dynamics usually work well as a team, a feature much sought after in the work context in the days of today.
Dynamic reading
Dynamic reading is a set of methods that, when applied, allow individuals to increase their reading speed. A regular reader can read an average of 150 words per minute, with a comprehension level of 60%. On the other hand, the dynamic reader can read about 800 words, comprising 80%.
Although a speed reader can increase reading speed by five or eight times, some experts do not advise the use of speed reading for students.
population dynamics
The concept of population dynamics is related to changes within animal or plant populations that happen over time.
These can be of natural origin, depending on the characteristics of the population, and also of external origin: change in the distribution (dispersion) of members of a population in space by emigration and immigration (dynamics of dispersal); change in population density (abundance) by reproduction or death (corresponds to the concept of population dynamics and, in a restricted time, to population density).
Since the ability to increase (birth) is not exactly equal to mortality, there are changes in the number of individuals within a population.
Population dynamics aims to develop models that allow predicting the evolution of a population.
dynamics in music
In music, dynamics refers to the use of different degrees of sound intensity. The quality of instruments and room acoustics have a certain influence on dynamic changes. Since the 16th-17th centuries, composers have been noting certain signs and dynamic indications (p', pp', mf', f', ff', growing', decreasing'), which are based on sound intensity relative.
