Objectives of Physics

Physics unearths the mystery of nature: Physics is the fundamental branch of science because its principles are the basis of other branches of science. For example, the principle of conservation of energy is a principle of physics used to explain the wide range of science starting from the structure of atoms to weather forecasting.

Although the main function of physics is to study matter and energy, the main objective of physics is to realize the rules of nature as well as unearthing the mystery of nature. At the beginning of the twentieth century, physicists discovered that electrons revolve around the positively charged nucleus of an atom. Subsequent experiments proved that the nucleus consists of protons and neutrons. Now the physicists have discovered that protons and neutrons are formed of smaller particles.

The study of physics helps not only to understand and explain natural events but also its application plays a vital role in other branches of science. At present physics is at the center probably because of its application in other branches of science. The discovery of electron at the end of the ninetieth century made possible to invent the electron microscope which has brought about a revolution in material science and Cytology.

In physics, there is the development of theories and application mathematics at the same time it has practical application and engineering application too. Physics is very essential to give fundamental explanations and form an idea about Chemistry, Geology, Astronomy, Meteorology, etc. In addition, there is a wide application of methodology and instruments of physics in Biology, Oceanology, Psychology, and Medical Science.

Physics describes the laws of nature: The natural world that we live in follows certain laws e.g. Newton’s law of gravitation, the law of conservation of energy, etc. Since our childhood, we have been acquiring these laws through our personal experiences which are very essential for our life. We cannot change the function and laws of nature but can utilize them. For their proper utilization, we need sufficient knowledge about them. Moreover, physics is the science that studies on this earth for innovation.
