How to Prepare for CBSE Class 11 Physics Practical Exam
Physics is one of the most important subjects for students who want to pursue a career in science, engineering, or medicine. Physics helps us understand the natural phenomena around us and the principles behind them. However, physics is not just about learning theories and formulas. It also involves conducting experiments and activities that demonstrate the concepts and laws of physics in action.
That is why CBSE Class 11 Physics Practical exam is an essential part of the curriculum. It tests the students' ability to perform experiments, record observations, draw graphs, calculate results, and answer viva questions. The practical exam carries 30 marks out of the total 100 marks for physics. Therefore, students should prepare well for the practical exam to score high marks and improve their overall percentage.
But how can students prepare for CBSE Class 11 Physics Practical exam effectively? What are the tips and tricks to ace the practical exam? Where can they find the best resources and guidance for the practical exam? In this article, we will answer all these questions and more. We will provide you with a comprehensive guide on how to prepare for CBSE Class 11 Physics Practical exam and achieve your desired marks.

Know the Syllabus and Marking Scheme
The first step to prepare for CBSE Class 11 Physics Practical exam is to know the syllabus and marking scheme. The syllabus contains the list of experiments and activities that students have to perform in the laboratory. The marking scheme tells how many marks are allotted for each experiment, practical record, viva voce, etc.
The syllabus and marking scheme for CBSE Class 11 Physics Practical exam are given below:
Two experiments from Section A (one from each group)
Two experiments from Section B (one from each group)
Practical record (experiment and activities)
Viva on experiments and activities
The list of experiments and activities for Section A and Section B are given below:
Section A: Experiments on Mechanics
To measure the diameter of a small spherical/cylindrical body using Vernier callipers.
To measure the internal diameter and depth of a given beaker/calorimeter using Vernier callipers and hence find its volume.
To measure the diameter of a given wire using a screw gauge.
To measure the thickness of a given sheet using a screw gauge.
To measure the volume of an irregular lamina using a screw gauge.
To determine the radius of curvature of a given spherical surface by a spherometer.
To determine the mass of two different objects using a beam balance.
To find the weight of a given body using the parallelogram law of vectors.
Using a simple pendulum, plot L-T and L-T graphs. Hence, find the effective length of a secondâs pendulum using an appropriate graph.
To study the variation of the time period of a simple pendulum of a given length by taking bobs of the same size but different masses and interpreting the result.
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 gravitational pull of the earth and study its relationship with the angle of inclination (Î) by plotting a graph between force and sin Î.
Section B: Experiments on Properties of Matter, Heat, Sound, Light, Electricity, Magnetism, Electronics, etc.
