These three dimensions make up what's called orientation, which can be measured. And the third dimension is any angle that the top takes on as it spins around. The flat surface the top is spinning on is the horizontal axis. This line is called an axis, and in this case, the vertical axis. Think of a line going through the center of the while it's spinning. Since the outward force of the spinning disk pulls equally in all directions, the top stays balanced. One force is gravity, which wants to pull the top down, and if the top starts to spin too slowly, gravity will become stronger than the force generated by the spin. The physics behind this is that the spinning motion generates an outward force that can counter other forces. When the top spins fast enough, it remains in an upright position and resists any attempt at falling over.
