Question

Which of the following variables will we actively change over multiple trials during this lab to see their impact on pendulum period?

1) Length of the pendulum
2) Mass of the pendulum bob
3) Amplitude of the pendulum swing
4) Angle of release
5) All of the above

Answer 1

The variables that can be changed to see the impact on pendulum period are the length of the pendulum, the amplitude of the pendulum swing, and the angle of release.

Step-by-step explanation:

The variables that can be actively changed over multiple trials during this lab to see their impact on pendulum period are:

1. Length of the pendulum: When the length of the pendulum is changed, the period also changes. Doubling the length doubles the period, and decreasing the length decreases the period.
2. Amplitude of the pendulum swing: Changing the amplitude of the swing does not have a significant effect on the period, especially if the amplitude is less than about 15°.
3. Angle of release: The angle of release also does not have a significant effect on the period of a pendulum.

Therefore, the correct answer is 3) Amplitude of the pendulum swing.
