Having this vision in mind we have created ¡°Perfect Physics: Std. XI¡± as per the new textbook of Maharashtra

State board. It focuses on not just preparing students from examination point of view but also equipping them

to understand and appreciate the beauty of Physics as a subject.

Every chapter, segregated subtopic-wise, encompasses all textual content in the format of Question-Answers.

Textual Exercise questions, Intext questions, ¡®Can you tell¡¯, ¡®Can you recall¡¯, ¡®Try this¡¯ and ¡®Activity¡¯ are

placed aptly amongst various additional questions in accordance with the flow of subtopic. To offer students

better understanding of the concept discussed in question, ¡®Reading between the lines¡¯ (not a part of the

answer) has been provided as deemed necessary. Numericals along with their step-wise solutions are covered

under heading of Solved Examples at the end of each subtopic. Quick Review has been provided to map the

chapter effectively in students¡¯ minds. Formulae covered in the chapter are compiled together as Important

Formulae at the end of the chapter. Exercise and MCQ sections are added to enable students assess their

range of preparation and knowledge of each topic. NCERT Corner and Notes are introduced to cover

additional bits of relevant information on each topic as seemed required.

While ensuring complete coverage of the syllabus in an effortless and easy to grasp format, emphasis is also

given on active learning. To achieve this, we have infused several key features such as, Gyan Guru, Enrich Your

Knowledge, Connections, Additional information and QR Codes. Also, additional sections such as Apply Your

Knowledge and Competitive Corner pave the way for a robust concept building.

The following screenshots will walk you through the core features of this book and elucidate how they have been

carefully designed to maximize the student learning.

Enrich Your Knowledge presents

fascinating information about the

concept covered.

This is our attempt to create interest in

the students about the concept.

Connections

For points (ii) and (iv)

In chapter 3, you have studied about angular

velocity (?) and centripetal force.

Gyan Guru illustrates real life

applications or examples related to the

concept discussed.

This is our attempt to link learning to the

life.

Enrich Your Knowledge

Since sizes of degrees on the Celsius scale and the

Absolute scale are identical, any one of the scales can

be used for temperature difference.

Connections enable students to

interlink concepts covered in different

chapters.

This is our attempt to encourage

students to appreciate the subject as a

whole.

Reading between the lines

Reading between the lines provide

elaboration of concept or missing

fragments of concept.

This is our attempt to explain the

concept without deforming the length of

expected answer.

NCERT Corner

NCERT Corner covers additional

information from NCERT textbook

relevant to topic.

This is our attempt to bridge the gap

between NCERT and State Board textbook,

thereby benefitting students in their

preparation of National level competitive

examinations.
