Dear aspirant, Physics, science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In the broadest sense, physics (from the Greek physikos) is concerned with all aspects of nature on both the macroscopic and submicroscopic levels. Its scope of study encompasses not only the behaviour of objects under the action of given forces but also the nature and origin of gravitational, electromagnetic, and nuclear force fields.

Chemistry, the science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes. Every substance, whether naturally occurring or artificially produced, consists of one or more of the hundred-odd species of atoms that have been identified as elements. Although these atoms, in turn, are composed of more elementary particles, they are the basic building blocks of chemical substances; there is no quantity of oxygen, mercury, or gold, for example, smaller than an atom of that substance. Chemistry, therefore, is concerned not with the subatomic domain but with the properties of atoms and the laws governing their combinations and how the knowledge of these properties can be used to achieve specific purposes.

All the best

Hope this helps

Hello Hifzurrahamaan

Physics and Chemistry do have a lot in common but they are indeed quite different from each other.  Both are "Hard" sciences that depend on the scientific method and experimental design.  I don't think one is a subset of the other discipline but rather they both overlap in many ways.

I would like to point out a real difference I have seen between chemists and physicists. Chemists seem more down to earth than physicists. They stay in the world of the known more than physicists do. Physicists are more like philosophers than chemists. They want to know the reasons and causes of everything that makes up reality in the world and even the cosmos. The field of chemistry includes both scientists that are oriented toward research and engineers who use their knowledge and skills to produce big "Factories" to produce chemical products. Physicists are pretty much all oriented toward basic research and theories of reality. I have never heard of a Physics Engineer. Put differently, physicists never seem to make the transition from basic theory and philosophy to money making business propositions.
