Fundamental Physics

Physics is a Fundamental Science.

Fundamental Laws of Physics cover a wide Varity of application scenarios and apply to many other coveted branches of sciences. Physics itself is study of laws of nature and the behavior involved with the universe. Physics is considered to be basic branch of science since its laws may apply to other branches of science.

In short terms, Physics involves study and interaction of matter with one another. The range of Study of Physics is from micro atomic particles to study of outer galaxies.

In the study of physics the first principle involved is to measurement a physical quantity. For this we utilize predefined units and dimensions. These are defined as per internationally accepted terms and definitions. Thus Units and Dimensions play an important role in study of physics.

For quantifying any physical quantity suitable experiments are performed. These experiments are then compared to already known laws. Once the relations between the experiments are matching to logical reasoning of known laws the experiment is published and then accepted to scientific community.

Example to get a relation between speed and velocity of an object, first the physical quantity speed and velocity are defined. A sample object is chosen and experiments are performed on the object. Its speed and velocity is measured. And after suitable numbers of experiments are done, using mathematical formulas and relation is obtained between speed and velocity of an object.

This is then repeated with objects of different shape size and in different environments. Once the relation is verified successfully the relation is then accepted as a law and it’s accepted by scientific community. In this way our knowledge of physics grows and we understand more about laws of physics. 

Certain advanced areas of physics are astrophysics, biophysics, environmental physics, theoretical physics, nanotechnology and semiconductor physics.
