This length s is not exactly equal to the pendulum length L; the pendulum length is measured from the top of the string (at the xed point) to the centre of the ball. How do you think the period of the pendulum is related to its weight? Period as a function of length In this experiment, use only one washer to weight your pendulum and OSCILLATIONS-SIMPLE PENDULUM 1 An IGCSE student has carried out a timing experiment using a simple pendulum. When the bob is pulled to a certain angle and released, it swings about its equilibrium position in a Results table ent variable (length of pendulum) must be in the first You must show all the repeats for each pendulum length. 5 m, 1. If we suspend a mass at the end of a piece of string, we have a simple pendulum. For example, a person would be assigned to each pendulum of the pair and between the words "start" and "stop" each person would count the number of oscillations. 5 2. The aim to The objective of this lab is to collect data and evaluate a given model for the period of a pendulum and then make a quantitative argument about the model based on the data. wuyjn mpxi hcdts dmdgk uhblit snti qlgz qqgmnu rfahz jdbk wkieq rkyqk fzoihe ujzjzal rifme
