Question

obtain the equation of motion for Foucault pendulum

Answer 1

Answer

when we suspended a 28Kg brass-coated lead bob with a 67-metre long (wire from the dome of the Panthéon, Paris. The proper period of the pendulum was T=17sec

So

The equation of motion we find is:

$m \ddot{r}θ+2\dot{r}\dot{θ}=2m\dot{r}Ωsinλ.$
