Value of Physics in daily life

Physics deals with the study of inanimate objects and their behaviour. Objects are inanimate things, and they can have motion and states. Physics studies different aspects of matter like its motion through space, the time taken, the energy, and force it takes to move. Thus the study of physics involves analyzing the matter and understanding the behaviour of world and universe.

It is one of the most important streams of science which plays an important role in our daily life. The tools, machinery, and instruments that we use in daily life are governed by principles of physics. The working principles of all gadgets used by us like mobile, computer, bicycles, cars, etc are governed by various laws of physics.
Another usual example of application of physics in our daily life is electricity and electrical circuits. The law of Newton is very useful to walk, and run. The concept of friction is always counted to load the packages. Physics is also applied to the human body. The electrical signals are exchanged between the neurons, which help to understand the stream of biology, called neurology.

The other most common example of day to day physics is dealing with pressure. When vegetables are cooked in a pressure cooker, the air gets compressed in a small vessel and the out burst (whistle) is the result of pressure created in cooker. When a sealed cold drink bottle is opened, the cork of the bottle pop or fly, it is because of the pressure inside the bottle. .

The laws of physics dissertation help to understand the behavior of liquids. Liquids change their phase on heating and cooling. When water is heated continuously in a pan having a lid, it evaporates at its boiling point and soon the covered lid falls open because steam could not escape and exerts pressure on lid.

There are several other laws of physics, which make our life easier and convenient. They explain the cause and remedies and things to be understandable.
