A Brief Overview Of Class 11 Physics Portion

Leaping into standard 11 is a huge stride considering the fact that it is the starting point of a student’s career and hence, is a crucial year in the life of a student. A student is presented with three options as soon as he is promoted to standard 11- Science, Commerce and Arts. The majority of students tend to go ahead with students looking at past year statistics and other relevant records. Physics is an essential part of science according to the CBSE curriculum and is a subject that must be paid attention to, going forward.

In this article, the CBSE standard 11 Physics portion is skimmed through to provide better exposure to the student. It is extremely important to analyse the CBSE Class 11 Physics Syllabus before starting the preparation.

Topics Covered

  • Units and Dimensions- It gives a basic idea about the measurement criteria that is used in various parts of the world. This chapter comes up with the idea of a fundamental unit which is basically the unit that does not depend on other quantities.
  • Vectors- This chapter differentiates between quantities that have a magnitude and direction and the ones that only have a magnitude. It provides a brief insight into concepts such as vector manipulation to learn about the changes happening in our surroundings.
  • Kinematics- It states the behavioural pattern of a point object that is subjected to a one-dimensional motion. Friction is usually neglected in this chapter and a nearly perfect environment is assumed to arrive at the three fundamental equations of kinetics that is utilised to study most of the other systems in a similar situation.
  • Laws of motion- This chapter describes the effect of application of an external force on a point object. Newton’s three laws of motion which are quite famous among modern day physicists have been covered in this chapter along with their implementation in numerical problems. External forces such as friction are also considered while formulating the equations utilised in this chapter.
  • Work, Energy and Power- Moving forward, a brief summary of how the external forces change the potential of a body and result in energy disparities is discussed in this chapter. A lot of new definitions pop up in this chapter which might be confusing for the students at an initial stage but an in-depth study about them helps in concept building.
  • Rotational Mechanics- Laws of motion do not give an idea about a particle that is made to rotate in the presence of an external force. Since, rotation comes into picture in this chapter, variables that were unheard of till standard 10, are suddenly hurled at the student. The concept is entirely new and hence, an average student might have a difficulty understanding the subject matter at the first glance. With due exposure, the student would be able to grasp the concept of rotational mechanics with ease.
  • Gravitation- A brief look into the interaction between any two particles in space and their attraction towards each other due to the phenomenon known as gravitation. It also gives a clue about the interaction between an average human being and earth. When most of the readers were kids, a question might have struck them which is “why a human being is attached to the ground while a bird is able to fly”. This chapter delves into that question and puts an end to the reader’s inquisition giving them a fair enough conclusion.
  • Properties of bulk matter- Elasticity is a fundamental property of matter. A common misconception that most people have is rubber being more elastic as compared to iron. This statement becomes ironic after going through this chapter and deciphering elasticity in a lucid manner. The chapter also contains a section about springs and their behaviour under applied forces. Springs have always been a matter of fascination for a lot of students and this chapter provides a crystal clear view about the mechanism of a spring.
  • Thermodynamics- The haphazard motion of the minute gas particles that are invisible to the naked eye end up causing unexpected phenomena. Thermodynamics is the study of the turbulence caused in the surroundings due to various factors like energy exchange and heat radiated. The three laws of thermodynamics along with the zeroth law offer a clear understanding of the properties of heat transfer.
  • Behaviour of perfect gases- The concept of ideal gas is emphasized in this chapter. An ideal gas is assumed to have negligible to no interaction between its molecules and henceforth, serve as a perfect model to investigate the properties of a gas without taking a lot of external effects into consideration. Later in this chapter, a real gas is also defined along with the equations that govern the movement of a real gas considering certain approximations.
  • Oscillations- The periodic motion of a particle is covered in this chapter. The nature of waves and oscillations is discussed at length which gives a student a basic idea of the particle undergoing rapid movement. The equations are derived keeping in mind the necessary conditions for a body to oscillate.

All these chapters are basically the essence of the entire textbook. The syllabus encapsulates some of the research subjects in a simpler manner. Studying the chapters is really important as it forms the fundamentals of advanced physics taught in universities and colleges across the world.

This article sheds a brief light on all the chapters present in the syllabus. A student who wants to know what he should expect while reading a certain chapter may consider going through the detailed analysis of each and every topic. Physics is considered to be a numerical heavy subject and hence, the concepts that a student learns through the syllabus could be tested on analysing the equations better as well as solving numerical questions. Together, these two form the building block of a student’s physics knowledge.
