I was holding a rubber band ball in my hand earlier and tossing it up in the air at about eye level. I noticed that I could see the shape of individual rubber bands on the axis of rotation on the outside of the ball but the edges of the ball were blurry. This got me thinking.. is a ball spinning slower near the axis than it is at the outer edge? Is the earth spinning faster at the equator than it is at the poles? If speed is d/t then the math makes sense to a layman like me that the ball would be rotating slower at the center and faster on the edges. Please help.
edit: holy shit. balls are fascinating.

Another way to look at it is at a racetrack. If everyone started off side by side and ran at the exact same speed, the people closer to the middle will finish 1 revolution or 1 lap before the person on the outside. If they were to lock arms and run, the people further out would have to run faster to keep up.
