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 various 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. It will also look at possible flaws and errors. Introduction: In order to determine how the mass, amplitude …showed first 75 words of 965 total…

…showed last 75 words of 965 total…reaches its maximum height. Possibly a computer could get these exact times and having a various rulers with exact measurements. By these results, it shows that two of the hypothesis' put forward were correct, that a change in amplitude would not change the period of a swing and that the length of string will change the period of a swing. If the mass is changed, there is no change in the period of a swing.
