the rotation of the Earth swing the pendulum unless acted upon by an outside force (Isaac Newton) and will spin in the direction of the Earth because it is suspended in mid-air.

Gravity and inertia.. Gravity pulls it down. Inertia makes it keep going in the same direction. Once it gets too high, gravity pulls it back down again. Inertia makes it keep going in the same direction. The process just keeps repeating.

The rotation of the earth. Also the length of the strng, the mass of the weight, etc...
At the equator, it stays stable, away from the equator, it rotates.
