Research Question What impacts the period of a pendulum for small swings? [1] Dependent Variable Period Independent Variable Mass Length (68.5 cm),

Control Variables Release Angle (5°) A pendulum’s period is Hypothesis affected by its mass. The period changes as

Prediction the mass changes.

Length (from the pivot point to the center of mass)

Mass (50.15 g), Release Angle (5°) A pendulum’s period is affected by its length. The period changes as the length changes.

⋯ Release Angle Mass (50.15 g), Length (68.5 cm)

A pendulum’s period is affected by its release angle. The period changes as the release angle changes.
