Physics, abbreviated as PHYS, is the study of the universe and our suroundings.  Matter and energy are the two basic concepts that exist through the universe making them the foundation of physis.  There are two main branches of physics, pure physics and applied physics. 

Pure physics is the study of matter and energy and their relationships (properties) to each other. 

Applied physics is a combination of pure physics and engineering put to practical use.
