What is Physics ?

"Physics Is the branch of science that deals with the study of matter and energy and there mutual relationship is known as Physics"

For example:-
1:-  Atomic Bomb Is the invention of Physics
2:-  Tv and other electronic devices are working on the principal of Physics
3:-  Capacitor,Inducter and Resistor plays important role in the field of Physics
4:-  Airplane, Railways Business and the other transport are working on the principal of Physics
5:-  Computers, laptops and the other devices are working on the principal of Physics
6:-  Rockets and Satellite also working on the principal of Physics
7:- In our daily life wheels, pulies also working on the principal of Physics

Branches Of Physics :-

1   Mechanics Physics :-

                                             Mechanics Physics is the branch of physics which deals with the Motion of  Materials  object under the action of forces is known as Mechanics Physics.

2   Optics Physics :-

                                      Optics physics is the branch of physics which deals with the nature of light properties is known as Optics Physics.

3  Thermodynamics Physics :-

                                                           Thermodynamics Physics is the branch of Physics which deals with the transformation of heat energy into other forms of energy is known as Thermodynamics Physics.

4   Atomic Physics :-

                                        Atomic Physics  is the branch of physics which deals with the study of structure and properties of in individual of Atom is known as Atomic Physics.

5   NuclearPhysics :-

Ohm's Law :-

      "Stats That Voltage is Directly related to current and Resistance"

Mathematically :-

           V = IR

           I  = V/R     

           R = V/I

Graphically  :-
