The branch of science which deals with the interaction of matter and energy is called physics. Finally, for completeness, we briefly present the three branches of physics, developed in the 20th century, that constitute the so called modern physics, i. Definition of physics, major branches, classical physics, modern physics. Physics and its branches quantum mechanics physics. Physics deals with the combination of matter and energy. Thermodynamics is the study of heat and other forms of energy, and of the conversion of energy from one form to another. Further sub physics branches are mechanics, electromagnetism, thermodynamics, optics, etc the rapid progress in science during recent years has become possible due to. Between the branches of classical and modern physics we can highlight acoustics, optics or mechanics in the most primitive field, and cosmology, quantum mechanics or relativity in the most recent applications classical physics describes theories developed before 1900, and modern physics events occurred after 1900. Electromagnetism is the branch of science concerned. Classical mechanics is concerned with bodies acted on by forces and bodies in motion and may be divided into statics study of the forces on a body or. Optics is the study of the nature and behavior of light.
