Physics studies natural phenomena related to mechanics, thermology, acoustics, optics, electricity and modern physics.
We will see below the objectives expected from the study of physics and its divisions.
It is to unravel the mysteries of nature in order to make us understand more about our relationship with the world and the universe, in order to show that there are no theories, postulates, paradigms or absolute models about this relationship, all of which are relative and susceptible. to new discoveries and understandings.
To improve human living conditions through technology, because with it it is possible to carry out work in a more practical way, thus obtaining a better quality of life.
Getting people to analyze the cause and effect of a given phenomenon as a relationship and not referring to everything as something related to their beliefs and superstitions, but making them understand that there is a difference between the two.
Quantities Physical Quantities is the classification of everything that varies in its quantity, that is, they imply units of measurement that generally vary from region to region. Such quantities are divided into two, as follows:
Scalar quantities – composed of real numbers (positive and negative), accompanied by their respective unit of measurement.
Vector quantities – characterized by having module, direction and sense.
Branches of Physics
Didactically, physics is divided into:
Mechanics –studies movement and its causes;
Thermology – studies heat;
Acoustics – studies the sound;
Optics – studies light;
Electricity – studies electricity;
Modern Physics – studies everything related to physics after 1900.
