Objective
Investigate the principles of simple harmonic motion using a simple pendulum.
Materials
- String
- Weight (e.g., metal washer, small rock)
- Protractor
- Timer
- Ruler
- Notebook for recording data
Instructions
- Construct a simple pendulum by attaching a weight to one end of a string and securing the other end.
- Measure the length of the string and the angle of displacement using a protractor.
- Release the pendulum from a small angle and use a timer to measure the period of oscillation.
- Repeat the experiment with different string lengths and angles of displacement.
- Record and analyze the data to understand the relationship between period, length, and amplitude.
- Present your findings in a report, discussing the principles of simple harmonic motion demonstrated by your pendulum.
