Scope of Physics Scope of Physics is vast as it covers quantities with length magnitude as high as 10 40 m or more( astronomical studies of universe) and as low as 10- 14 m or less( study of electrons, protons etc). Similarly the range of time
scale goes from 10-22 s to 10 18 s and mass from 10-30 kg to 10 55 kg.
Physics is broadly divided into two types based on its scope- Classical Physics and Modern Physics. Classical physics deal with the macroscopic phenomena while the modern physics deals with the microscopic phenomena.
Macroscopic Domain
Macroscopic domain includes phenomena at large scales like laboratory, terrestrial and astronomical. It includes following subjects: o
Mechanics – It is based on Newton’ s laws on motion and the laws of gravitation. It is concerned with motion / equilibrium of particles, rigid and deformable bodies and general system of particles. Examples, o Propulsion of rocket by ejecting gases o Water / Sound waves o Equilibrium of bent rod under a load
