Physics is the subject which is the base of all the sciences. The laws of Physics are applicable in every field of sciences.
Physics is the science of exact measurement. We can measure the distance between points, mass, and weight of solids as well as liquids and various other measurements with the help of formulas developed by Physicists.
Actually, Physics is the study of phenomenon occurs in the universe. Laws of Physics are based on the fact of this nature. These laws show how the universe changes continuously.
Laws of Physics are not applicable to some specific things. These can be applied to the whole universe. These laws do not state. These are changeable and can be modified.
Definition of Physics:
“Physics is the study of properties of matter, energy, and their mutual relationship.”
Branches of Physics:
In Mechanics Physics we study the motion of various objects and also study under what forces various objects moves.
Thermodynamic Physics is the study of heat, energy, and the relationship between heat and energy.
It is the study of the properties of light. Reflection, Refraction, and wave motion of light is studied in optics Physics.
Lenses, Microscope, Telescope, etc. are the applications of Optics Physics.
4.Electricity and Magnetism
Here we study the properties of electricity and magnetism individually and also their relationship. The study of electricity and magnetism is also known as Electromagnetism.
5.Atomic and Nuclear Physics
It is the advanced form of Physics. Atom Physics is the study of individual atom and Nuclear Physics is the study of Radioactivity.
It is cleared from the name of the branch that it is the study of solid-state objects. The motion of solids and the equilibrium of solid objects are discussed here.
It is the branch of Physics in which we understand the Biological system by using the principles and methods of Physics. Read the complete guide about Biophysics.
CT-SCAN and MRI are the applications of Biophysics.
Applications of Physics:
All these are the applications of Physics that made our life easier :
1. The most powerful and modern computer technology become possible due to the advancement in Physics.
2. The satellite communication system and GPS (Global Positioning System) is based on Physics.
3. X-ray, MRI, and CT Scan, etc. all are the applications of Physics.
