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.

The entirety of the ball rotates at the same rate. The ball’s surface moves fastest at its equator, slowest at its poles, just like the Earth–at the equator the Earth is moving at around 1,000 mph or so. At mid latitudes (where most people live) it’s about 800 mph. At the poles it’s zero.
