Hi
Assume that the Foucault's pendulum is located in N pole and is oscillating from W to E (x direction). The Z axis is vertically up. The force acting on the bob as it moves from equilibrium position towards E is in the -y direction causing the plane of the pendulum to rotate in CW direction (as viewed from above). When the bob retraces its movement (from E to equilibrium position) the force is in the + y direction, i.e. opposite to the previous case.
Then how does the plane of the pendulum rotate in a consistent manner (i.e. clockwise)
TIA
