Physics is a term originating from the Greek “physis" which means "nature”. It is the science that studies the laws that govern natural phenomena susceptible to being examined by observation and experimentation, seeking to fit them into logical schemes.
Some of the best known physicists in history are Galileo Galilei, Isaac Newton and Albert Einstein.
Physics is a fundamental science that develops based on theories and experiments. They are part of the main theories of physics: classical mechanics (description of the movement of objects), quantum mechanics (determination of measures of magnitudes), relativity (space-time and gravity relations) and electromagnetism (study of electricity and magnetism).
Classical Physics encompasses all theories and knowledge developed until the end of the 19th century, encompassing the principles of classical mechanics, wave mechanics, thermodynamics and electromagnetism.
Modern Physics encompasses theories and concepts from the 20th century, highlighting quantum mechanics, relativity and experimental physics (investigation of physical phenomena using processes experimental).
The areas into which Physics is divided are: Acoustics (study of sound); Electricity (studies electricity); Mechanics (study of movement); Nuclear (studies nuclei and nuclear matter); Optics (study of light).
