Simple Pendulum - determining acceleration due to gravity
In this experiment a steel ball on a string can be swung by applying an impulse using the mouse. Its period can be measure either using a stop-watch or the gate timer which automatically times a complete swing. The string’s length can be altered by using a winder. A vertical ruler allows the string’s length to be measured. The U-gate of the timer can be raised and lowered to allow the period of the swing to be measured for different lengths of string. Thus a graph of T2 against length can be plotted the gradient of which can be used to calculate the acceleration due to gravity.
