I saw a video of a windmill a few minutes ago and they are quite fast.
But then i thought “Is the tip of the rotorblade as fast as the the point furthest in the middle?”
Let me explain the best i can:
So if you move 10km/h, after 1h you are 10km farther than before. Thats logical.
But with regards to the rotor blade, the point furthest in the middle moves less far than the one all the way outside.
Does that mean that the points move at different speeds even though they’re part of the same body?
Where is my mistake in thinking?

One thing I’d like to add is that this is all talking about linear speed. If you consider speed in this case as angular velocity, which is degrees(or revolutions, or radians)/second, then all values on the same blade should be the same.
