Luke Wyatt Experiment 1 4/10/06 Experiment 1: Measurement of gravity by simple pendulum Risk Assessment The Experiment had a very low risk as it only has one moving object and is powered by me giving it potential energy rather than any thermal or electrical energy working on it. Therefore the only potential risk in this experiment is as stated below 1. Mechanical risk – As there is a moving component (pendulum) which could swing and hit other objects or if pulled on could topple the apparatus. Experiment Aim The aim of the experiment was to find the acceleration due to gravity by measuring accurately the time it takes for the simple pendulum to make 20 revolutions and then calculating the period of the pendulum which can be used to find the acceleration due to gravity. Below is a list of all the apparatus which was used in the experiment Clamp Clamp Stand Stopwatch Cotton Thread Metal Bob Cork Pads Pointer Meter Rule Below is a diagram of how the apparatus was set up in order to collect my results. 1of 6
