# How to crack class 11th Physics in full swing?

Class 11th Physics is all about building a solid foundation for the physics studied at higher levels i.e. 12th and beyond. It is essential to grasp all of these concepts with unparalleled clarity at this stage to avoid any unnecessary confusion in the times ahead.

## Syllabus for class 11th physics

The CBSE 11th Class Physics Syllabus is as follows –

• The physical world around us, what is the nature of laws that govern the functioning of things, scope of technology, societal developments in the modern world, what is the need for measurement in today’s world, what are the fundamental units of measuring, errors while measuring quantities, what is the difference between accuracy and precision, what is dimensional analysis, what the applications of dimensional analysis are, wide array of instruments used for the purpose of measuring
• What is motion, what are the different types of motion that we observe around us, plotting graphs depicting relations between position, time, distance, speed, velocity and acceleration, using differentiation and integration to derive the formulas and gain an analytical understanding of the concepts, special focus on uniform accelerated motion, what are scalar quantities, what are vector quantities, properties of vectors, basic operations of addition, subtraction and multiplication in terms of vectors, different types of products associated with vectors, how is motion in a plane affected, detailed study into circular motion (uniform and non-uniform), what is projectile motion

• Experiments – measuring the diameter of certain objects using practical devices, measuring thickness, measuring volume, finding out radius, finding out mass, finding out weight, finding out the length of the pendulum, studying the relation between force and normal to the force, studying the motion of objects on planes of varying inclinations, viscosity, elasticity, plotting cooling curves, surface tension
• Activities – least count, measuring the mass of a body, plotting graphs of given data, studying limiting friction, understanding the conservation of energy practically, studying constant dissipation of energy. Making sense of the entire scope of motion of a projectile

## Tips to get amazing marks in the Physics exam

• Try to understand every topic after a complete visualisation of every aspect of it. Most of the chapters in class 11th physics are graphically sound which makes the conceptualisation process easier
• Understand the syllabus well – Analyse the syllabus well and know the weightage of each chapter so that you can invest time and effort accordingly. Without a complete and in-depth knowledge of the syllabus, you would not be able to pinpoint the exact areas of scoring
• Segregate your strong and weak points. Put in more effort in the areas of shortcomings but at the same time, study the weak areas smartly.
• Revise each concept of every chapter at least three to four times so study accordingly with ample buffer time.
• Make a copy of all the formulas and theories to grasp them better.
• Practice regularly.
• Pay close attention to the constructions, plotting of graphs and making of figures as they bind the answer well.
• Manage your time wisely – Never over exert but also don’t sit ideal in your free time for long hours.
• Take sufficient breaks in between long hours of study sessions.
• Make notes wherever possible to increase your retention power for longer periods.
• Do a thorough reading of the books also to answer the multiple-choice questions well.
• Make a realistic timetable.
• Refer to multiple books at one time to gain a full view of the content.

There is absolutely nothing to worry about physics in class 11th as long as you focus on every aspect of it equally and practice daily. The need for remaining in constant touch is immense and must never be overlooked
