>Calvin and Hobbes problem still confusing me
So there's a comic strip whete Calvin's dad explains to him that for a wheel to turn the outside travels at a grater speed than the inside.
It does this because the inside of the wheel has a shorter distance to travel than the outside. If they both traveled at the same speed than it would shred the spokes.
All of this I understand so far.
What I don't quite get is how a "solid" object is able to go at different speeds at the same time.
A wheel turns on itself, so this isn't really an issue.... And if you have a camera attached to the wheel it would look like it's not moving at all.

So finally my question... Does a spinning wheel move on itself or not?
