SPH 3U: An Investigation of the Pendulum Corey McCormick

Question: What are the relationships between the frequency of a simple pendulum and its amplitude, and length?

Prior Knowledge:

Variable SI Unit Definition
Amplitude cm Distance from the equilibrium position to the maximum displacement.
Frequency Hz
The number of cycles per second.

Label the amplitude and length of the pendulum below.

Materials:
„h List the materials you have been given (and any other you decide to use)

1 A meter Stick
2 A 30cm ruler
3 A piece of tape
4 100cm+ of string
5 a washer
6 2x desks
7 2x chairs

Hypotheses:
„h Complete the hypotheses before the experiment.

a) If the amplitude is increased, but the mass and length remain constant then the frequency will increase because the added amplitude allows the pendulum to gain more acceleration on the initial drop giving the pendulum a higher cycle per second...
