Why does a cone-shaped object, when placed on its side on a flat surface, rotate about the end with a smaller diameter?

Question

Examples include a light bulb, a screw, a nail, etc.

I intuitively know how these objects behave, but I’m having trouble putting it into words/reasoning about it.

Is it because of the tilt? The diameter difference (this causes the tilt)?

Answer 1

Diameter difference. The entire item must turn the same number of times no matter the size of the two ends. But the fat end will travel farther in the same number of revolutions.
