Arjun is investigating how changing the string length ($L$) of a simple pendulum affects its period of oscillation ($T$). He has access to a retort stand, cotton string (20 cm – 100 cm), a 50 g metal bob, a meter rule, a stopwatch, and a protractor.
Theoretical Model: $T = 2\pi\sqrt{\frac{L}{g}}$ where $g = 9.81\text{ m/s}^2$
Formulate a query exploring the relationship between string length and period, specifying variables and units.
Explain the scientific importance of defining a testable problem in Arjun's pendulum study.
Provide a clear 'If... then... because...' prediction justified by relevant physics equations/concepts.
Specify name, units, and measurement/control methods for each variable class.
| Type | Variable Name | Measurement / Control Method | Units |
|---|---|---|---|
| Independent | |||
| Dependent | |||
| Control 1 | |||
| Control 2 |
Explain how timing 10 oscillations improves data reliability compared to a single swing.
