 By measuring the period of oscillation of the pendulum as a function of the length in the string we can find a  value for the acceleration due to gravity. The video shows you how we measure the different quantities that are important in the experiment, the length of the string, $L$, the angle, $\theta$ and the period of oscillation,​ $T$. Note that we measure the length several times and the period for 10 oscillations to try to minimize **random** errors. Notice that we use the computer as a stopwatch: we will be using the computer frequently in this course to make measurements and record data. By measuring the period of oscillation of the pendulum as a function of the length in the string we can find a  value for the acceleration due to gravity.
