DescriptionPéndulo de Foucault-20110815-125224-2191-1000d-a2b2.jpg |
Un péndulo de Foucault es un péndulo esférico que puede oscilar libremente en cualquier plano vertical y capaz de oscilar durante mucho tiempo (horas). Se utiliza para demostrar la rotación de la Tierra y el efecto Coriolis. Se llama así en honor de su inventor, Léon Foucault. En esta fotografía se muestra el péndulo que se encuentra en el Panteón de París. Su importancia histórica radica en que con él se hizo la primera demostración, en 1851. El péndulo se fijó a la cúpula del Panteón de París; medía 67 m y llevaba una masa de 28 kg. Una vez lanzado, el péndulo oscilaba durante 6 h. El periodo es de 16,5 s; el péndulo se desviaba 11° por hora. Su ciclo de giro completo dura algo más de 32 horas. |
