An Investigation That Determines How Mass, Amplitude and Length Affect the Period of a Simple Pendulum.

Synopsis:This investigation will show how the mass, amplitude and length affect the period of a swing. The process that is needed is included and variou ... rious hypotheses will be put forward. Whereby the mass will vary between 0.065 kg to 0.1535 kg, the amplitude will vary between 10 and 20 cm, and the length of string will vary between 0.1 and 2.57 m. ... m.
