SIMPLE HARMONIC MOTION AND THE SIMPLE PENDULUM Task 1 Aim To carry out an experiment of simple harmonic motion using a simple pendulum and determine the acceleration due to gravity, to verify the equation T = 2??(l/g) and show the relationship between time period and length. Method The apparatus is set up, as above, the string must be measured carefully with a ruler to minimise any error; the length should start off fairly short at about 0.2m for example. The bob should be secure. A table should be made for results, this should include length, time (twice), average time and time period (= average time/20). The pendulum is set into motion by a gentle push, some practice in doing this and also counting and timing the oscillations beforehand may help to achieve greater accuracy. The angle of amplitude should be kept similar if not the same for each experiment, to make sure the forces acting on...
