The Jharkhand Academic Council (JAC Board) has been regularly updating the syllabus of all the subjects in Class 11 as it is considered a crucial phase in a student’s academic career. Sincere and dedicated studies help students to prepare well for the Class 12 Board examinations. Considering this factor, we are providing a detailed summary of JAC Board Class 11 Physics syllabus in this article.
A comprehensive understanding of the syllabus will surely help students to come up with an effective time table for the exam and cover all the chapters within a reasonable amount of time. Furthermore, it is important to revise the chapters multiple times before exam to score good marks.
The JAC Board has distributed the Physics subject into two papers. One is a theoretical paper, while the other is a practical paper.
Paper – I is a theory paper carrying a total of 70 marks with a 3-hour time limit.
Paper – II is a practical paper worth 30 marks.

Gist of the theory syllabus
The difficulty level and the amount of time required to cover each unit and chapter varies. Therefore, students must try to revise their basics well before going ahead with the new chapters while studying for the exam.
The next step would be to prioritize the chapters according to their weightage of marks. Each unit in the JAC Board Physics Class 11 Syllabus 2021 has been assigned with appropriate marks. Units 1, 2, and 3 (Physical World and Measurement, Kinematics, and Laws of Motion) have the highest 23 marks and must be given the most importance by students.
Units 4, 5, and 6 (Work, Energy, and Power, Motion of a System of Particles and a Rigid Body, and Gravitation) are worth 17 marks when taken combined. Finally, Unit 10, Oscillation and Waves, is worth ten (10) marks.
Practical Syllabus of JAC Board Class 11 Physics
A list of experiments prescribed by the JAC Board Physics Class 11 Syllabus 2021 has been provided below. Students are required to maintain a journal/report book to note down their findings in a tabular format with units at the column header for each experiment. They can further draw graphs wherever required, perform the relevant calculations, and arrive at a conclusion at the end of the experiments.
Given below is the list of practicals/experiments:
Section A:
- To measure the diameter of a small spherical/cylindrical body using Vernier calipers.
2. To measure internal diameter and depth of a given beaker/calorimeter using Vernier calipers and hence find its volume.
3. To measure the diameter of a given wire using screw gauge.

10. To study the relationship between the force of limiting friction and normal reaction and to find the coefficient of friction between a block and a horizontal surface.
- To find the downward force, along an inclined plane, acting on a roller due to the gravitational pull of the earth and study its relationship with the angle of inclination (θ) by plotting graph between force and sin θ.
Section B:
- To determine Young’s modulus of elasticity of the material of a given wire.
- 2. To find the force constant of a helical spring by plotting a graph between load and extension.
3. To study the variation in volume with pressure for a sample of air at constant temperature by plotting graphs between P and V, and between P and 1/V.
4. To determine the surface tension of water by capillary rise method.
5. To determine the coefficient of viscosity of a given viscous liquid by measuring the terminal velocity of a given spherical body.
6. To study the relationship between the temperature of a hot body and time by plotting a cooling curve.
7. To determine the specific heat capacity of a given (i) solid (ii) liquid by method of mixtures.
8. (i) To study the relation between frequency and length of a given wire under constant tension using sonometer.
(ii) To study the relation between the length of a given wire and tension for constant frequency using sonometer.
- To find the speed of sound in air at room temperature using a resonance tube by two resonance positions.
The goals of these experiments and activities included in the JAC Board Physics Class 11 Syllabus are to improve the understanding of students regarding the principles learned from the theoretical topics. These experiments will also provide a solid basis for further study in the subject.
The aforementioned experiments will aid students in developing the capacity to adapt their physics knowledge and understanding to new settings. They will assist students in developing a scientific mindset and abilities in the practical parts of handling apparatus, recording observations, and drawing diagrams and graphs through the study of physical sciences.
Activities/Projects:
Apart from experiments, there would be a few activities which would be required to be performed by students as part of their project each semester. Following is the list of those activities:

Under the regular guidance and supervision of the Physics teacher, all students will be required to complete the aforementioned activities/projects. Students must write a technical report that includes an abstract, some theoretical discussion, experimental setup, observations with tables of data obtained, findings analysis and discussion, deductions, conclusion, and so on.
Practical File:
Students will be required to maintain a Physics practical file during the academic session. Teachers would be assessing these files and give marks accordingly.
Overall, the redesigned JAC Board Class 11 Physics Syllabus 2021-22 aims to improve conceptual clarity of the students and help them understand the interlinking of Physics and other subjects.
We hope that this article about JAC Board Class 11 Physics Syllabus has been beneficial to students in planning their studies. Being well-versed with the syllabus will also assist them in making an effective study plan for the exam.
