A point connected to a light mass is called a simple pendulum suspended with mass and fixed support. Simple pendulum experiment A simple pendulum consists of a particle of mass ‘m’ usually called bob, suspended from a rigid support with the help of an unstretchable, mass less string. A practical simple pendulum has a small metallic bob suspended from an unstretchable thread and its length l ‘is the distance between the point of suspension and the center of gravity of the bob. When a simple pendulum is set to oscillate it moves to and fro about it’s mean position between the two extremes A and B with constant amplitude as shown in the figure. Figure 2 showing position the mean and extreme position of a simple pendulum When we plot the horizontal displacement and the time on a graph paper the curve obtained would be in the form of a wave .
