Cálculo de la Incertidumbre en la Medición Visual de los Parámetros de un Péndulo de Foucault

We present a method for determining the uncertainty in the measurement of parameters that describe the dynamics of a Foucault's pendulum. In the document, we review how these parameters can be obtained. Then, we propose a method for evaluating the uncertainty in their determination. We illustrate the method with experimentation made on a 28m height pendulum located at 20° 35' north latitude.
