## Important Theories and Topics in Physics Class 11

1. Classical Mechanics- This focuses on the study of particles and their motion. It studies how much velocity they travel with. Their velocity is much less than the velocity with which light travels.

2. Relative Theory- Given by Albert Einstein, the theory talks about how all objects in motion are relative to each other. It talks about the motion of particles that travel with a velocity close to that of light.

3. Thermodynamics- It is the theory that studies heat, temperature and how heat is converted into work.

4. Kinetic Theory- This theory studies and explains the behaviour of gases. It is assumed that gas consists of atoms that are rapidly moving. The random movement of particles due to the presence of large intermolecular space is explained in the theory.

## How to Use the NCERT Book While Preparing for Exams?

• The NCERT textbook is the main and the most important textbook prescribed by the CBSE board. Most of the questions in the school and the board exams come from the textbook. It is important that the students are extremely thorough with the textbook if they want to score full marks in the exam.

• Students should go through all the chapters before the exam. Reading all the chapters is extremely important. You should also refer to the important points at the end of each chapter which can be helpful. It is also recommended that you make notes from the chapter as it will help you understand and memorise the chapter in a better way.

• Attempt all the questions from within the chapter and at the end of each chapter. You can assess your answers or refer to the solutions pdf given by Vedantu for help in answering them.

• Make sure to thoroughly practice all the diagrams in the book. They are extremely important for the students to know.

• Attempt the numericals from the book and examples as well. They can be asked directly in the exam.

### Important Tips for the Exam:

• The students should always have a timetable. The timetable will help the students to keep a track of their syllabus and also help them analyse how much time they need for each subject or topic. Having a timetable will also help them keep a track of the chapters they cover and make sure to not skip any topic.

• Having a schedule and timetable means being regular with your studies and giving preparation the time it needs. It is also important to understand that you cannot finish everything at once, so breaks are an important part of the schedule as well. Make sure to give yourself regular breaks and take time to refresh yourself. This will help you to also study better once you get back from your break. Always start a new topic refreshed as it will help you retain better.

• Write and revise as much as possible. Making notes is important and an effective way of preparing for the exams. Writing and learning help you memorise and understand better. You are able to learn the topic better. Make sure to write all the formulas and derivations as they are asked in the exam. Writing and learning them will make it easier for you to answer them in the exam as well as you will know how to write them.

• Make summaries for topics and chapters- This will help you to revise for the exam in a better way. Writing down summaries will help you highlight important bits from the chapters and present them in a concise form. This helps in keeping all the syllabus in one place and also focuses on the most important bits of the chapter. While revising you can just go through your notes and summaries instead of looking through the whole chapter and wasting time.

• Practice enough numerical questions- There are questions in the NCERT textbook that you must practice and also in the Vedantu Solutions PDF. There are enough practise questions for the students to attempt. This will help you get a grip on the formulas and attempt numericals. Numericals can be high scoring if the students have enough practice.

• Attempt all the questions and examples in the NCERT textbook. The NCERT textbook is the most important book for students of Class 11 and 12. In boards and school exams, most questions are asked from the NCERT textbook or are based on the same kind of pattern of questions. The students should be thorough with all the questions are given at the end of each chapter and also extra questions or examples that may be given within the chapters. If you are thorough with these questions it will be easy for you to attempt any questions of this kind and other variations of it. Practising NCERT questions can help you score good marks.

• Attempt sample papers and papers from the previous years. This will help you understand the kind of questions that can be asked in the exam and how you should answer the exam. They are available online and in the sample pdf as well. Always track yourself while attempting the sample paper as this will help you manage your time well. Assess yourself after each attempt so that you know how you can better your performance and which topic needs more practice.

• Make sure to practice all the diagrams and graphs while preparing as well. It is also important that you do not overwork yourself while you are preparing for the exam. Before the exam you feel confident in the subject, give yourself some rest. Do something else besides studying. Refresh your mind. It is also important to get a full night’s sleep before the exam and restfully. Only revise what you feel is important before the exam.

• The day before the exam, prepare your bag and whatever you require for the exam. Do not leave this for the morning of the exam. Make sure that you rest, take a break and sleep on time before the exam day. If you need to revise, select a time that you do not feel will interfere with your rest. Keep yourself away from distractions as any little confusion may make you doubt your preparation and lead to unwanted stress. Focus on what you know and know it well.

• While attempting your exam make sure to attempt all the questions. Attempt the questions that you are sure of first. Do not waste time on any question that you are not sure of. Make sure that you highlight the formulas and important words and lines in your answers. Make sure to keep your answer sheet neat. Having a well-presented paper is always better and gives you an edge over other students.

• Make sure to have enough time to revise your answers after writing the paper. Manage your time well and leave some time for revision. This is extremely important for numericals and calculations. Revising your answers can help you recognise your mistakes if there are any and give you the chance to rectify them. Revising can save you from a lot of marks being cut.

• Attempt all the questions in the order that they are given in the question paper and according to the sections. Do not answer questions in a haphazard order. This may lead to confusion for the teacher assessing your answer sheet and can lead to marks getting deducted, managing your time well to attempt all the questions in the given precise order.
