PRACTICAL 15 To prove that time period of a simple pendulum is independent of (i) mass of the pendulum (ii) amplitude of the vibration. VIVA VOCE 1. What is the objective of the experiment? Ans: The objective is to demonstrate that the time period of a simple pendulum remains constant irrespective of changes in its mass and amplitude. 2. How is the time period of a pendulum defined? Ans: The time period (T) of a pendulum is the time taken for one complete oscillation, i.e., the time it takes for the pendulum to return to its starting position. 3. Explain how you varied the mass of the pendulum during the experiment. Ans: We kept the length and amplitude of the pendulum constant while changing the mass by attaching different weights at the bottom of the pendulum bob. 4. What did you observe when you changed the mass of the pendulum? Ans: Despite changing the mass, we observed that the time period of the pendulum remained constant. 5. Why does the time period remain constant
