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
