Effect of Length
- If the length is changed, the time period also changes.
- A longer pendulum has a longer time period.
Effect of Mass of the Bob
- If the bob's mass is changed but length kept fixed, the time period does not change.
Conclusion
- Time period depends on length but not on mass.
- All pendulums of the same length have the same time period at a given place.
- This property is used to measure time.
