1.1 Purpose of The Pendulum ExperimentsAs a pendulum`s length increases, the time that a pendulum returns to original position, referred to as a period, gets increased after its motion. The period of a pendulum is not simply proportional to the length of a pendulum, and it is necessary to understand the characteristics of its dynamics based on the analysis of a system model. In this experiment, to understand the relations between simple and compound pendulums, the analysis on a simple pendulum having a concentrated point mass is firstly conducted, and then the analysis on a compound pendulum having a specific shape is also carried out. In addition, in the case of a compound pendulum, the concept of the center of percussion and the effect of friction dnd to a pendulum`s percussial motion are experimentally studied.
