Scope of Physics

Physics is the key to all science. It is the fundamental branch of science because the foundation of other subjects is based on the principles of physics. For example, the principle of conservation of energy is a basic principle of physics used to explain the wide range of science starting from the structure of atom to weather forecasting. Starting from Engineering to Medical Science, Astronomy to Oceanology, Biology to

Psychology the instruments of Physics are used. For the systematic study of physics, we can divide it into the following branches : (1) Mechanics (2) Heat and thermodynamics (3) Sound (4) Optics (5) Electricity and Magnetism (6) Solid State Physics (7) Atomic Physics (8) Nuclear Physics (9) Quantum Physics and (10) Electronics
