## Introduction to ISC Class 11 Physics Syllabus

ISC Class 11 Physics Syllabus is a vital study resource for students preparing for the ISC Class 11 Physics board examination. Students should know the entire Syllabus of each subject before they start preparing for their test. Hence to help the candidates, subject experts at Extramarks have created a comprehensive curriculum for the ISC Class 11 Physics Syllabus. In-depth knowledge and understanding of ISC Class 11 Physics Syllabus will help prepare a proper study schedule for the examination.

## ISC Class 11 Physics Syllabus

Before preparing for any examination, the students need to plan for a study timetable, and without a complete curriculum, it can be difficult for them to create one. Hence, the Syllabus is essential for examination preparations to acquire better results

### ISC Class 11 Physics Syllabus: Examination Pattern & Chapter Weightage

ISC Physics Class 11 paper is divided into two parts:

Examination Paper I-Theory

There will be no choice in the overall paper for Class 11 ICSE Physics Syllabus. Students are supposed to answer all questions compulsorily but with an option of internal choice in two questions which carry 2 marks each, two questions of three marks each, and all the three questions of 5 marks each. As mentioned in the table below:

 Sl No. Unit Name Marks 1 Physical World and Measurement 23 Marks 2 Kinematics 3 Laws of Motion 4 Work, Power and Energy 17 Marks 5 The Motion of the System of Particles and Rigid Body 6 Gravitation 7 Properties of Bulk Matter 20 Marks 8 Heat and Thermodynamics 9 The Behaviour of Perfect Gases and Kinetic 10 Marks 10 Gravitation Total Marks 70 Marks

Examination Paper II-Practical

This will consist of 30 marks. The subdivision is mentioned below:

• Practical work duration is 3 hours – 15 marks.
• Project work weightage – 10 marks.
• Practical file weightage – 5 marks.

Extramarks recommend students complete all the experiments from the below-given list:

• To measure the diameter of a spherical body(Curved body) using Vernier Calipers. Calculate the dimensions with suitable significant values. Also, measure the volume using a graduated cylinder and compare the two.
