Practical Syllabus

SECTION - A

Experiments

1. To measure diameter of a small spherical/cylindrical body and to measure internal diameter and depth of
a given beaker/calorimeter using Vernier Callipers and hence fi nd its volume.

2. To measure diameter of a given wire and thickness of a given sheet using screw gauge.

3. To determine volume of an irregular lamina using screw gauge.

4. To determine radius of curvature of a given spherical surface by a spherometer.

5. To determine the mass of two diff erent objects using a beam balance.

6. To fi nd the weight of a given body using parallelogram law of vectors.

7. Using a simple pendulum, plot its L-T graph and use it to fi nd the eff ective length of second's pendulum.

8. To study variation of time period of a simple pendulum of a given length by taking bobs of same size but
diff erent masses and interpret the result.

9. To study the relationship between force of limiting friction and normal reaction and to fi nd the
co-effi cient of friction between a block and a horizontal surface.
10. To fi nd 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 θ by plotting graph between force and sin θ.

Activities

1. To make a paper scale of given least count, e.g., 0.2 cm, 0.5 cm.

2. To determine mass of a given body using a metre scale by principle of moments.

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.
