What is physics?

Physics is a natural science that studies matter, its motion, and behavior through space and time, and that studies the related entities of energy and force.

More broadly, it is the general analysis of nature, conducted in order to understand how the universe and everything in it behaves.

Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe works.

Physics also makes significant contributions through advances in new technologies that arise from theoretical breakthroughs.

For example, advances in the understanding of electromagnetism or nuclear physics led directly to the development of new products such as computers, television, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus.

Here are some main branches of physics:

Classical Mechanics
Thermodynamics
Electromagnetism
Relativistic Mechanics
Quantum Mechanics

The definition of physics is the study of the physical plane of matter, motion, force, and energy. The root word of physics is Phys- and is Greek for "nature" and "natural order." Physics itself is studying the natural world and the interactions between objects and energy in any given environment.

In ancient Greece, early scientists did not have anything more than their senses to help them study the world around them. These scientists often studied their environment through touch, taste, smell, sight, and sound. During the 17th century, people like Galileo, Copernicus, and Newton revolutionized science with breakthroughs of physics through the laws of gravity, the sun-centered theory, and the discovery of atoms. With modern technology and advances in the scientific method, physics incorporates things that are not observable to the naked eye.
