An Investigation of the Factors Affecting the Period of a Pendulum :: Papers

An Investigation of the Factors Affecting the Period of a Pendulum I could investigate the following factors * Angle of displacement * Length of mountain chain * Pendulum weightiness I am tone ending to investigate and see if varying the length of pull out will affect the period of the pendulum. My anticipation is The longstanding the string the longer the period. The period will be longer as the pendulum has farther to travel. My theory is demonstrated below. Pendulum A has a shorter string. This gives it a shorter period. Pendulum B has a longer string and has a much larger period as it has farther to travel to get from X to Y to X which is one period. IMAGE I made my prediction based on a previous experiment I have done. The length affected the period as stated above and I estimate this will happen again in this experiment. I looked at a clock with a pendulum to see how it worked. I found that to change the speed of a second you adj ust the length of the pole which the pendulum hangs from, so I also based my prediction on that as it is the same principle. I set up a trial experiment to test out the following * Which angle of displacement to use (e.g. 90) * How many readings to take * Which lengths of string to measure (e.g. each 10cm) * Where to carry out the experiment (on a desk/floor etc..) To ensure the test is fair I am going to * Use the same piece of string * Use the same weight pendulum (preferably the exact same pendulum) * Make sure the string is measured accurately To ensure the test is safe I am going to * Use a sensible angle of displacement * Not to swing the pendulum near others To ensure the test is accurate I am going to
