What is Physics?


Physics is a natural science that involves the study of matter and its motion through spacetime, as well as all related concepts, including energy and force, heat, sound, light, magnetism, electricity & the composition of atoms. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves.

Physics can be divided into 2:
  1. Physical Science
  2. Biological Science
Physical science concerned with the properties & behaviour of non-living matter.

Biological science deal with living organisms.
