The Central Board of Secondary Education provides a well-structured syllabus for the practical examination. The Physics practical consists of various interesting experiments, which are also essential for their 12th standard practical exam. So, students must perform their Physics practical exams diligently to perform better in the final exam. The Physics Practical Class 11 is given here to help students prepare for their exam. It carries a total of 30 marks. Along with the projects and experiments, students must also prepare for the viva questions on the experiment which carries 5 marks. Students should practice graphs and diagrams as they are essential parts of the exam.

3. To plot a graph for a given set of data, with proper choice of scales and error bars.

4. To measure the force of limiting friction for rolling of a roller on a horizontal plane.

5. To study the variation in range of a projectile with angle of projection.

6. To study the conservation of energy of a ball rolling down on an inclined plane (using a double inclined plane).

7. To study dissipation of energy of a simple pendulum by plotting a graph between square of amplitude and time.

Section B

1. To observe change of state and plot a cooling curve for molten wax.

2. To observe and explain the effect of heating on a bi-metallic strip.
