Physics is the scientific study of matter and energy and how they interact with each other. This energy can take the form of motion, light, electricity, radiation, gravity . . . just about anything, honestly. Physics deals with matter on scales ranging from sub-atomic particles (i.e. the particles that make up the atom and the particles that make up those particles) to stars andeven entire galaxies.
How Physics Works: As an experimental science, physics utilizes the scientific method to formulate and test hypotheses that are based on observation of the natural world. The goal of physics is to use the results of these experiments to formulate scientific laws, usually expressed in the language of mathematics, which can then be used to predict other phenomena.
The Roleof Physics in Science: In a broader sense, physics can be seen as the most fundamental of the natural sciences. Chemistry, for example, can be viewed as a complex application of physics, as it focuses on the interaction of energy and matter in chemical systems. We also know that biology is, at its heart, an application of chemical properties in living things, which means that it is also,ultimately, ruled by the physical laws.
Introduction to importance of physics in daily life:
Physics is the branch of physics in which we deals about the measure of the different physical quantities. So many physical quantities play the important role in our daily life, such as mass, volume, purity, preparing of food, etc. In our daily life there is a very important role of physics.
Importance ofPhysics in Daily Life:
There are several things, which have great importance in our daily life. Out of these, physics is the one of them. The main and the important form of energy that is electrical energy is only and only due to the physics. We cannot image the life without electricity. The formation of clouds in nature is based on the physical phenomenon called evaporation. Physics is also appliedin our body. Due to electrical signals, which carry the sensation, to mind, we are able to see, listen or to feel the objects. In the cooking of the vegetables, some of the physical laws work. Even we choose the metal of the utensil on the behalf of physics. We generally use water as a coolant or as a heating liquid due to the high specific heat of water. Physics also explains the several form ofenergy and their transformation. Such as kinetic energy, potential energy, nuclear energy, etc. Even in the growing of plants the osmosis is used and the photosynthesis is used which is also explained by the physics. Physics gave us very important inventions such as our cars, bikes, watches, bulbs, LEDs, cell phones, TV, computer, laptops, VCD players, microwave ovens, cooking gas stoves, etc.Conclusion of Importance of Physics in Daily Life:Actually Physics is derived from a Greek word that means nature. The physical observations and the theories are consistent in nature. This is the theory, which makes the prediction of the results. Physics starts with the simple structures and then analyze the phenomenon. Now these days the physics has become indispensable. Physics pertains the newconcepts and the materials as solar cells, which are environment friendly, do not produce any pollution. It can creates the situations in which we can solve the several problems.
Physics deals with a wide variety of systems, there are certain theories that are used by all physicists. Each of these theories were experimentally tested numerous times and found correct as an approximation of Nature(within a certain domain of validity). For instance, the theory of classical mechanics accurately describes the motion of objects, provided they are much larger than atoms and moving at much less than the speed of light. These theories continue to be areas of active research; for instance, a remarkable aspect of classical mechanics known as chaos was discovered in the 20th century, three centuries...
