Explore the rhythmic motion of a pendulum and how its length impacts swing time. This project provides insights into periodic motion and energy transfer.
If the pendulum's string length is increased, then the swing time will also increase.

Cut the string to different lengths (e.g., 30cm, 50cm, 70cm).
Tie a washer at the end of each string.
Secure the other end of the string to a fixed point.
Pull the pendulum back and release it.
Use a stopwatch to measure the time for ten swings.
Record the time for each string length.
Compare the results for different lengths.
Analyze the relationship between string length and swing time.
Repeat experiments for accuracy.
Conclude findings and present them attractively.
Longer pendulums are expected to have longer swing periods due to increased travel distance.

Keep the swinging area clear of obstacles to avoid injury.
Use diagrams to show pendulum setup and measurements.
Explain how pendulum clocks work using this principle.
Demonstrate swings with real pendulums during presentation.
Longer pendulums have greater distance to travel, affecting their period.
Ensure the pendulum is released from the same height each time.
Yes, but this experiment focuses on length; additional weights can be an extension.
