Physics is the natural science that studies matter, its motion and behavior through space and time, and that studies the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.
While science as a subject is about understanding and seeking the knowledge of the entire universe, Physics can be considered as the integral subject to encourage any particular theory. In every research, physics is basically involved as a role of basic study. Physics is studying and understanding how nature works hence, every part of nature has physics in it.
Physics within itself contains sub-subjects on the basis of the energy(mostly). They are mechanical, optics, heat and temperature and waves. Physics can be studied in two ways: theoretical and experimental. Theoretical physics is all about hypothesis, theories and stating mathematical statements to prove those theories whilst experimental physics requires the report and conclusion of any theories by conducting the experiment. Physicist are the people who studies physics as major in their education and studies these theories. They are the ones who create ideas and theories for new inventions or hypothesis leading the world into a better understanding place to live in.
People who studies nature and understand their ways were always present, It wasn't until 1600s, those people would graduate their collage and mastered Phd to be called as Physicist. Before the era, the ancient Philosophers can also be considered Physicist. They all recorded their work for the development of the humanity as a whole and lots of great minds have contributed in this field such as: Galileo, Robert Boyle, Newton, Einstein, Tesla.
