Students conducted an experiment to examine how pendulum arm length ($L$, in cm) and bob mass ($M$, in grams) affect the period of oscillation ($T$, in seconds).
- Trial 1: $L = 25\text{ cm}$, $M = 50\text{ g} \implies T = 1.00\text{ s}$
- Trial 2: $L = 25\text{ cm}$, $M = 100\text{ g} \implies T = 1.00\text{ s}$
- Trial 3: $L = 100\text{ cm}$, $M = 50\text{ g} \implies T = 2.01\text{ s}$
- Trial 4: $L = 100\text{ cm}$, $M = 100\text{ g} \implies T = 2.00\text{ s}$
