|---|---|
| Two experiments — one from each section | 7 + 7 |
| Practical record — experiments and activities | 5 |
| One activity from either section | 3 |
| Investigatory project | 3 |

The current curriculum requires a record of at least 8 experiments with 4 from each section, at least 6 activities with 3 from each section, and the report of the investigatory project. Prepare the apparatus, formula, observation method, graph or calculation, result and likely viva questions while doing each practical.
1. A measurement is written as 12.40 cm. How many significant figures does it contain?
Answer: Four. The trailing zero after the decimal point is significant.
2. A car changes velocity from 10 m/s to 22 m/s in 4 s. What is its average acceleration?
Answer: 3 m/s², because a = (22 − 10)/4.
3. A net force of 18 N acts on a 6 kg body. Find its acceleration.
Answer: 3 m/s² from F = ma.
4. What happens to gravitational force if the distance between two point masses is doubled?
Answer: It becomes one-fourth because gravitational force varies inversely as the square of separation.
5. Why is the area under a pressure–volume graph important in a thermodynamic process?
Answer: For a quasistatic process, the area under the P–V curve represents the work associated with the volume change, with sign determined by the chosen convention and direction of the process.
6. In simple harmonic motion, where is the speed maximum?
Answer: At the mean position, where the displacement from equilibrium is zero.
How many chapters are there in CBSE Class 11 Physics for 2026–27?
The current CBSE theory curriculum contains 14 chapters, beginning with Units and Measurements and ending with Waves.
What are the Class 11 Physics theory and practical marks?
The current curriculum allocates 70 marks to theory and 30 marks to practical assessment.
Is there a CBSE Class 11 board exam like Class 12?
No national Class XI board examination is conducted like the Class XII board examination. Schools conduct the Class XI annual assessment while following the prescribed CBSE curriculum.
Why do some older pages show different Physics chapter numbers?
Older NCERT editions included an introductory chapter before Units and Measurements. Some legacy resource URLs retain that numbering. Follow the current 14-chapter sequence shown on this hub.
What should the Class 11 Physics practical record contain?
The current requirement includes records of at least 8 experiments, at least 6 activities, and the investigatory-project report.
Where can I practise competency-style Class 11 Physics questions?
XAM CONTENT provides Case Study, MCQ and Assertion–Reason practice across all 14 Class 11 Physics chapters. Use those after learning the underlying concept from the current syllabus and textbook.
