Based on Table 19, increasing the bob mass from 50 g to 200 g at a constant length of 0.25 m causes the period to: Experiment Context (Period of a Simple Pendulum): Students tested small-angle oscillations (< 5°) of simple pendulums, varying bob mass (m) and string length (L): Table 19: - Trial 1: Length = 0.25 m; Mass = 50 g; Period T = 1.00 s - Trial 2: Length = 0.25 m; Mass = 100 g; Period T = 1.00 s - Trial 3: Length = 0.25 m; Mass = 200 g; Period T = 1.00 s - Trial 4: Length = 1.00 m; Mass = 50 g; Period T = 2.00 s - Trial 5: Length = 1.00 m; Mass = 100 g; Period T = 2.00 s - Trial 6: Length = 2.25 m; Mass = 100 g; Period T = 3.00 s
