Physics Coursework Factors affecting the period of a Pendulum Possible Variables: Angle of pull back - I did a quick experiment (see below) and proved that this makes no difference. Type of string - this is a discrete variable and would not give good results for a graph. Mass on the end of the String - this would be a good choice, but after a quick experiment I decided that the length makes more difference. Length of the String (distance of centre of mass from pivot) - I will investigate this variable. Experiment to show the angle of pullback makes little or no difference Length: 50cm, Mass: 200g Angle of pullback/degrees Time for five oscillations/sec Attempt 1 Attempt 2 20 7.05 6.98 50 7.01 7.10 These readings are very similar and although this doesn't prove that the angle of pullback has no effect, it shows that within the accuracy of this experiment it has no effect. I think that this is because if you pull it back further, then...
