The branch of science that deals with the interaction of matter and energy are called physics. There are Two Main Branches of Physics, Classical Physics and Modern Physics. Further sub Physics branches are Mechanics, Electromagnetism, Thermodynamics, Optics, etc.
The rapid progress in science during recent years has become possible due to discoveries and inventions in the field of physics. The technologies of our modern society throughout the world are related to physics. For example, a car is made on the principle of mechanics and a refrigerator is based on the principles of thermodynamics.
Importance of physics in our daily life
In our daily life, we hardly find a device in which laws of physics are not involved.
Examples
- Pulleys are used to lift heavy loads.
- Electricity is used to get light, heat, and mechanical energy that drives fans and electric motors.
- Means of transportation such as cars and airplanes, domestic appliances such as air conditioners, refrigerators, vacuum cleaners, washing machines, microwave ovens, etc.
- The means of communication such as radio, TV, telephone, and computer are the result of applications of physics. These devices have made our lives much easier and faster and more comfortable than in the past.
- The computer is the invention of physics.
