What is Physics

                  What is Physics

Introduction To Physics 

In nighteenth century , physical sciences were dividedinto five distinct discipline ; physics, chemistry, astronomy, geology and metrology. The most fundamental of these is physics. In physics, we study matter, energy and thier mqtual interaction. The laws and principles of physics help us to understand  nature .

Today Physics , Daily Use of Science (Physics) in Our Life

The rapid progress in Science , during the recent years has become possible due to discoveries and inventions in the field of Physics , The technologies are the applications of Scientific principles .Most of Technologies of our modren society throughout the world are related to Physics , For Example , a car is made on the principles of mechanics and refrigerator is based on the Principles of thermodynamics.

     In our daily life, we hardly find a device where Physics is not involved . Consider pulleys that make it easy to lift heavy loads, Electricity is not only used to get light and heat but also mechanical energy that drives Fans and Electric motors etc. Consider the means of transportation such as car and Aeroplanes ; domestic appliances such as air-conditioners, refrigerators, vaccume cleaner, washing machines, and microwave ovens etc. 

Communication Devices ( Physics )

     Similarly the means of Communication such as radio, TV, Telephone, and Computers are the result of applications of Physics.

These devices have made our lives much easier, faster and more comfortable than the past. 

For example , think what a mobile phone smaller than our oaln can do? It allows us to contact people anywhere in the world and to get latest worldwide information. We can take and save pictures, send and receive messages of our friends. We can also receive radio transmission and use it as a calculater as well.
There are  Nine Branches of Physics

Side Effects of Science and Physics 

  However, the scientific inventions have also caused harms and destruction of serious nature. One of which is environmental pollution and the other is the deadly weapons.
