What is Physics and its common branches

1. What is Physics? Learning Objectives: Relate Physics to other branches of natural science Discuss the branches of Physics and its importance

2. Physics from the Greek  physikos meaning nature, natural or physical science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. Natural science that studies matter, its motion and behaviour through space and time and the related entities of energy and force. is concerned with all aspects of nature on both the macroscopic and submicroscopic levels .

3. Branches of Physics Classical Physics This branch of physics is mainly concerned with the laws of motion and gravitation. This branch of physics deals mostly with matter and energy. Modern Physics Modern physics is a branch of physics that is mainly concerned with the theory of relativity and quantum mechanics. In modern physics, energy and matter are not considered as separate entities. Rather, they are considered different forms of each other.

4. Branches of Physics 3. Nuclear Physics a branch of physics that deals with the constituents, structure, behaviour and interactions of atomic nuclei. 4. Atomic Physics . It is mainly concerned with the arrangement and behaviour of electrons in the shells around the nucleus . 5. Geophysics is a branch of physics that deals with the study of the Earth. It is mainly concerned with the shape, structure and composition of the Earth

5. Branches of Physics 6 . Biophysics studies biological problems and the structure of molecules in living organisms using techniques derived from physics 7 . Mechanical Physics is a branch of physics that deals with the motion of material objects under the influence of forces. 8 . Acoustics The word "acoustics" is   derived from a Greek word  akouen , meaning "to hear." a branch of physics that studies how sound is produced, transmitted, received and controlled.

6. Branches of Physics 9. Optics a branch of physics that studies electromagnetic radiation (for example, light and infrared radiation), its interactions with matter, and instruments used to gather information due to these interactions. 10. Thermodynamics Thermodynamics is a branch of physics that deals with heat and temperature and their relation to energy and work. 11. Astrophysics The word "astrophysics" is a combination of two Latin-derived words:  astro , which means "star," and  phisis , which   means "nature . “ as a branch of astronomy which is concerned with the study of universe (i.e., stars, galaxies, and planets) using the laws of physics.
