Detailed considerations are given for the motion of Foucault's pendulum suspended by a string from a support that can rotate freely. It is well-known that the vertical axis attached to the support of the pendrum rotates with uniform angular velocity due to Coriolis force induced by the rotation of the Earth. In an earlier work, one of the present writers derived an equation of motion for a load suspended from a slewing jib crane attached to a rotating vertical pole. This equation is applied to analyze the motion of Foucault's pendulum. It is shown that the centrifugal force abuot the suport may have a signifficant effect on the pendulum motion. Exact solutions are obtained and experiments on Foucault's pendulum are then conducted to confirm the theoretical predictions.
