AIM: To investigate how the length of a simple pendulum affects the time period for a complete swing (oscillation). VARIABLES: To keep the investigation as simple as possible, only two variables are going to be changed. Independent Variable: This is the length of the pendulum; it is independent, as it is not affected by other variables. Dependant Variable: This will be the time period (of one oscillation); it is dependant on the length of the pendulum. Control Variables: These variables will remain the same throughout the investigation in order to ensure a fair test. · Mass of bob · Angle of initial displacement (è) · Medium through which
