How to study Physics in 11th and 12th class
Importance of Physics as a subject of study
Physics is the most fundamental science. Knowledge of physics forms the base for all the branches of science and engineering. So for a science student it is very important to gain a basic knowledge of physics. That is why physics is a compulsory subject for science students in 11th and 12th class in India.
What is Physics?
It is very easy to define chemistry or biology. Chemistry is the science that studies material transformations which occur in nature. Biology is the science that studies about Life and Processes related to Life. Chemistry and Biology have therefore a very well defined area of interest.
But if we consider physics, we see, in physics we study about motion, force, energy, light, heat, gravitation, electricity, atoms, nucleus of atoms, molecules, planets, stars, universe….etc. the list is endless. Thus we see, in physics we study about atoms, nucleus, electrons, protons, neutrons, quarks... at one extreme, and we study about galaxies and universe at the other extreme. And in physics we also study about everything that comes in between these two extremes. So what is left? Nothing frankly! So we can say in physics we study about everything that is part of nature. That is why it is very difficult to define the scope of physics. But still if we like to define physics we can say “ Physics is that branch of science in which we try to understand the rules by which the nature works at every level of its existence (from microscopic to the mega macroscopic)”.
