Physics (derived from the Greek physikos) is a universal phenomenon that deals with all of nature. It encompasses the behavior of objects acting under the action of given forces as well as the nature and origin of gravitational, electromagnetic, and nuclear force fields. The fundamentals of Physics brings together a few comprehensive principles that govern the varied phenomena occurring in nature, as well as those synthetically produced by humans in a Physics laboratory.
Physics is the science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe.
Physics can be simply defined as basic physical science. Only recently, the branches of Physics and natural philosophy were used interchangeably in the study, discovery, and formulation of the fundamental laws of nature. With the rapid evolution of the modern sciences, the principles of Physics became a specialized field of scientific inquiry including interdisciplinary studies in astronomy, oceanography, planetary science, environmental science, chemistry, geology, and engineering.
Physics in Everyday Life
Physics is an integral part of the natural sciences. The different disciplines making up the latter, include life science, biochemistry, meteorology, classical mechanics, organic chemistry, statistical mechanics. All of them emphasize the role of physical laws and measurements.
The applied branches of Physics include astrophysics, geophysics, biophysics, psychophysics, quantum physics, computational physics, condensed matter physics, nuclear physics, statistical physics, engineering physics and so on.
Physics is the science of matter, motion and energy, typically expressed in the language of mathematics with economy and precision.
Classical physics largely accounts for the motions of macroscopic objects that are slower than the speed of light and for phenomena such as heat (thermodynamics)t, sound (acoustics), electricity and magnetism (electromagnetism), and light (optics). Relativity and quantum mechanics are recent developments that modify existing laws of general Physics vis-a-vis higher speeds, very massive objects, and elementary constituents of matter, such as electrons, protons, and neutrons.
Acing Physics Class 12 Exam
Classes 10 and 12 are two important stepping stones in the life of a student. Especially if you are an aspiring physicist who wants to pursue a course in Physics major and then go on to work in the Physics department of a prestigious university, you need good scores in your Class 10 and Class 12 Physics.
One of the easiest and most effective ways to prepare for the exams is to have a well-defined time table for revision. Once you have this, it is much easier to revise each and every topic thoroughly, albeit you will have to be completely familiar with the class 12 Physics syllabus first.
During this revision, it is advisable to collect previous years' question papers for Physics class 12. It is a great tool for self-assessment. You can even get together with your classmates in a study group and discuss these papers and exchange class notes.
Using Past Physics Question Papers
Most education Boards release copies of question papers from previous years. You can find them in your school library or even look online for a digital copy (PDF). Try to gather at least five years' worth of these papers and identify recurring themes in them.
Examiners tend to make minor changes to the style and format of the question papers. Compare past papers to have a better idea of what the examiner is really asking.
Prepare well those topics that you find more than once in the past papers. This also serves the added purpose of clarifying any topic you may have had a difficult time understanding in the classroom. Use your NCERT Physics class 12 textbook as a constant companion.

Overview of Solving Past Question Papers and Its Benefits
Following are the top reasons why you should seriously consider using past question papers to prepare well for your Class 12 Physics exam
- CBSE Class 12 Previous Years' Question Papers help you understand subtle changes in the composition of questions.
- These question papers help in understanding the exact nature of the exam.
- Mock tests with past papers help students track and improve their time management skills in the examination hall. This is a huge confidence-booster during the course of an exam.
Not only for class 12, but students can also use past questions papers to prepare for the class 10 Physics exam.
Let us explore some of these reasons a little more and also see how revision with past papers help in dealing with examination stress and anxiety in students.
Dealing with Examination Anxiety
With previous years' question papers, students have a better idea of what to expect in the actual exam which helps them prepare better. They develop an idea about the number of short and long answers required, marks distribution for each topic, etc. In effect, students gain confidence by solving more and more of these past papers, thereby reducing exam stress.
Identify Relevant Themes
The past question papers are based on the actual Board syllabus for Physics and cover almost all the important topics. Often, they come with solutions and marking schemes that help students analyze their areas of strength and weaknesses. Accordingly, students can focus on those topics that need more of their attention.
Practice Makes Perfect
Solving more and more of the question papers from previous years will stand you in good stead to refine your answers and make them as crisp and to-the-point as possible. Start at least two-three weeks before the commencement of your Board exam to maximize your chances of success!
Past papers have been solved by students of earlier batches. This knowledge also helps the current students to tackle difficult questions especially and put in more effort to do well in those. When students start seeing the difference in scores, particularly in the topics they lacked confidence in, it helps them relax and be more positive about the actual exam.
Improve Writing Speed and Style
With greater practice, your speed of writing is bound to improve. Also, students can work to make their writing styles more refined and readable that helps examiners when checking the answer scripts. They can also minimize their own silly mistakes.

Find Help with a Private Physics Tutor or Online Physics Teacher
This is not a necessary requirement. However, it is always a good idea to get your answers checked by an expert. Your personal Physics instructor can help you clarify concepts, leading to a better understanding of the theories of Physics. Who knows, perhaps, you may also come to love some of the chapters in applied Physics!
Approach your teacher with difficult questions that you are unable to answer properly. Tell them your learning needs and goals. Sometimes, all it takes is a different way of teaching to help you see that difficult things are not so difficult after all Check out online platforms such as Superprof to learn more about where to find a good Physics teacher.
