प्रश्न
Explain how the frequency of oscillation is related to the length of a pendulum and the amplitude of its oscillation.
उत्तर
The frequency of oscillation of a pendulum decreases with an increase in the length of the pendulum and vice versa. It is independent of the amplitude of the oscillation of the pendulum, provided the amplitude is small.

Define the terms : time period as related to a simple pendulum.
How is the time period of a simple pendulum affected, if at all, in the following situations:
- The length is made four times.
- The acceleration due to gravity is reduced to one-fourth.
How do you measure the time period of a given pendulum? Why do you note the time for more than one oscillation?
A simple pendulum completes 40 oscillations in one minute. Find its (a) Frequency and (b) Time period.

You can perform an interesting activity when you visit a park to ride a swing. You will require a watch. Make the swing oscillate without anyone sitting on it. Find its time period in the same way as you did for the pendulum. Make sure that there are no jerks in the motion of the swing. Ask one of your friends to sit on the swing. Push it once and let it swing naturally. Again measure its time period. Repeat the activity with different persons sitting on the swing. Compare the time period of the swing measured in different cases. What conclusions do you draw from this activity?
