Physics II


Physical science is known as the systematic study of the inorganic world, and physical science is divided into four very broad areas which are astronomy, physics, chemistry and earth sciences, as each of these fields is divided into fields and subfields, and physics science was established in its modern sense in the mid-nineteenth century as a synthesis For many ancient sciences, studies were based in large part on the realization that the different forces of nature are interconnected and in fact are transferable because they are a form of energy.

With the development of the twentieth century, physics is concerned with the structure and behavior of individual atoms and their components, while chemistry deals with the properties of molecules and their responses, and therefore there is a very strong link between physics and chemistry, but chemists tend to care more about the specific properties of different elements and compounds, while physicists are concerned with the general properties that are shared by all Materials.

The importance of physics
After talking about what is the science of physics, we must talk about the importance of physics, since physics is of great importance in daily life and this science relates to all sciences because it is the basis of the universe, and the importance of physics can be mentioned as follows:

Physics explains the scale of different quantities that play a vital role in daily life, such as size, weight, mass, distance, speed, etc. with standard units of measure.

Physics also explains the various forms of energy such as potential energy, nuclear energy, kinetic energy, wind energy, etc.

Physics helps to understand the electrical signals that bring a sense in the body to the minds through which things can be seen, heard or felt.

By understanding and studying the laws of physics and physics, a person can harness the various elements of nature such as water, fire, oceans, wind air, etc. and use it to his advantage and thus enhance the human lifestyle across generations.

The most important forms of energy found in physics.

Physics has given the world important inventions such as cars, lamps, satellites, bicycles, watches, mobile phones, television, computers, microwaves, cooking gas cookers and many more.

Science with a physical base can solve many crises facing the world, such as global warming, declining energy, overpopulation and natural disasters.
