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.

Yep.
I’m not a physisist or anything, but in my head I’m almost certain that they do, imagine you put a dot on the equator of the ball and a dot directly above it near one of the balls poles, and you spin it.
If different parts of the ball spun at different speeds, both dots would eventually become misaligned, but obviously they don’t. Both dots stay in the exact same position relative to each other during the entire spin.
