Observe the motion of an irregularly shaped object as it spins around its center of mass. The path of the spinning object reveals that the net force of gravity pulls down on the object at its center of mass. The center of mass of the irregularly shaped object follows a simple parabolic trajectory when the object is tossed into the air.
